makepkg : set sane umask before source extraction.

This fixes FS#9242 and FS#9362.

Set umask before the sources are extracted, and after the /etc/profile.d/*
files are sourced in handledeps.
This sourcing of profile.d files is why umask was moved to the build
function in the first place, as can be seen in commit ac965ed401.
