makepkg: fix consistency of downloaded sources permissions

Running 'makepkg -g' or 'makepkg' to download source files results in
different permissions on the files if the user has a non-default umask.

Put the umask definition at the "beginning" of the makepkg script to
ensure all files generated by makepkg have a 0022 umask.
