Fix detection of desktop packages on non-english systems

[lotharsm]

Currently, the script detects the availability of a suitable desktop environment/meta package by searching for the string installed when looking at the packages list.

This will fail on systems that use other languages than English by default. By enforcing LANG=C when launching apt list, we can circumvent this. Tested on a German installation right now.

To preserve compatibility with older versions and stay as close to sh as possible, shouldn't env LANG=C be used instead?

[lotharsm]

Well, I haven't thought about preserving this level of compatibility since at least now we aim at current development builds... How do you want to achieve this with env LANG=C? Setting LANG=C for the entire run of the script?

[codic12]

The env command allows you to set env variables for the current command. Example: env X=Y cmd
It's more universally supported on other shells than the classic syntax, as it is an executable (/usr/bin/env on Manjaro), so can be run within other shells...

Thanks!

Should work fine.
