In S_incpush, omit subdirs when PERL_IS_MINIPERL.

The new logic in S_parse_body that loads lib/buildcustomize.pl in
miniperl relies on lib being in $INC[0], which it won't be if we've
loaded version- and architecture-specific directories before lib.

Since miniperl isn't installed and can't do dynamic loading, it
doesn't really need those subdirectories, so skip loading them
for miniperl.
