Michal Koutný bac567a53b mkosi: Use distro-invariant rootprefix
Distributions may be build with various configs, e.g. customized
rootprefix. It'd be unmaintanable to have specific mkosi.build for each
supported distro. Hence, make the build script flexible yet distro
oblivious.

# all the way to the installed files, reset them to one of 0644 or 0755
# so the files keep those permissions, otherwise details of what umask
# was set at the time the git tree was cloned will leak all the way
# through. Also set umask explicitly during the build.
