feat: add c wrapper replacement for sh wrappers

Replace a sh wrapper by a binary wrapper.
Call the original shell script.

fix: shebang in environment wrapper files

fix(environment): check directory exists before copying files

feat: Replace original paths in extra files with the ones in environment

This is for example usable for share/application desktop files, to
point to the environment binary instead of the original binary.
Then the program will be started with environment from the environment
package.
