fix: resolve some issues with install.sh

[mozzieongit]

Some people don't use sudo or have curl, sed or wget installed by default.
This adds a check, if sudo, curl and sed are installed and changes wget
to curl as this is the mostly used command in the script. If sudo is not
installed it uses su.

The printf was missing a newline at the end, which resulted in the eval
line being appended directly to the end of the previous line. This is
similar to the problem from #56.

Closes: #175

I should probably wait for the dependabot PRs to be merged.

Why does cargo test -p atuin-common --lib suddenly fail? It failed on my machine, too.

But now it works again. I just re-ran it.
Weird.

EDIT:
I ran it multiple times now. It randomly succeeds or fails at different tests. (Even with other commit states)

Could you share the logs from the failures please? Maybe some of the env var stuff is being non deterministic
