ptxdist: improve umask handling
Currently any umask other than 0022 is not really supported. There is no
check but strange things may happen, either at build-time or at runtime.
Improve this by:
- setting the umask to 0022 if it it currently more permissive
- fail with a clear error message if it is more restrictive
Expand the documentation to explain the new behaviour.
