support updating package.ymls that use git sources

[yacn]

changes

• Updates yupdate to support updating package.ymls that are using git sources as the url.
• Adds --yml argument so that the if block at the top of the main function is used.

testing

testing showing yupdate checks for package.yml existence and that the file must have the extension .yml

isaac@xps13 ~/packaging/hub $ ../../git/etc/ypkg/yupdate 2.14.2 "git|https://github.com/github/hub.git" --yml does-not-exist.yml
Specified file does not exist
isaac@xps13 ~/packaging/hub $ cp package.{yml,yaml}
isaac@xps13 ~/packaging/hub $ ../../git/etc/ypkg/yupdate 2.14.2 "git|https://github.com/github/hub.git" --yml package.yaml 
package.yaml does not look like a valid package.yml file

I may be wrong but I guess that python-argparse need to be enabled and reintroduced in the repo if this patch gets merged.

Nah argparse is part of the standard library. LGTM
