Detect installed paths and update PATH and LD_LIBRARY_PATH accordingly

[duanehutchins]

• Detects existing lib/* paths and adds them to LD_LIBRARY_PATH
• New functionality to pass colon-delimited regex patterns via LD_LIBRARY_REGEX_PATTERNS, and matching directories will also be included in LD_LIBRARY_PATH
• Detects existing "bin" and "sbin" directories and adds them to PATH
• To fix bugs with mismatching variables during build/deploy:
  • BUILD_DIR is used as base directory for writing to export (used by other buildpacks during build).
  • HOME is used as the base directory for writing to .profile.d (used by app after deploying)
• This PR also includes PR Remove deprecated option and use noninteractive instead #36 to fix the --force-yes is deprecated warning. (thanks @reacuna)

This PR will satisfy several reported issues/pulls: #10 #16 #20 #27 #28 #36 #38

@duanehutchins I tested this with https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb and it did not add it to the path. The issue here is that it installs naturally into /usr/local/bin, not /usr/bin and is thus available in /app/.apt/usr/local/bin which is being missed.

Is anything blocking this from upstream? 👩‍🔬

It's been a while, but this PR would be wonderful to get in 😢

@KevinBrolly apologies if you aren't associated with this project -- just hoping someone from heroku could comment on this PR. The above fixes issues for me -- makes it possible to install chromium dependencies with an entry like this in Aptfile

gconf-service libappindicator1 libasound2 libatk1.0-0 libatk-bridge2.0-0 libcairo-gobject2 libgconf-2-4 libgtk-3-0 libnspr4 libnss3 libx11-xcb1 libxcomposite1 libxcursor1 libxdamage1 libxfixes3 libxi6 libxinerama1 libxrandr2 libxss1 libxtst6 fonts-liberation

Without it LD_LIBRARY_PATH seems to be incorrect and chromium fails to find libcairo ...

I'd be interested in updating the PR to address any concerns so it could be merged if could know what the concerns were that prevented merging this a year ago?

Hey guys, tonight/tomorrow I will update this PR (and duanehutchins/heroku-buildpack-apt) to include newer commits from this repo and resolve any conflicts. I'll also add /usr/local/bin/ as per @mmerickel's note above.

Hopefully, @heroku will be more willing to merge after that, and if any contributors are reading this, please let me know if there's any steps I should take to get this PR merged.

👋 - it's now 2021. @schneems - We could really use this (if you're still at Heroku that is).
