pjproject_bundled: Fix compile of pjsua so it handles audio

In order for pjsua and its python binding to actually negotiate
audio for the testsuite tests, it needs g711 and resample.  The
pj* libraries themselves do not.  Unfortunately, pjproject relies
on a brand new libresample that most distros don't ship so we need
to use the libresample already bundled with pjproject.  Only the pjsua
executable and the _pjsua.so python library are linked with it so it
shouldn't interfere with asterisk itself.

Also it was pointed out that apply_patches couldn't handle multiple
patches that depended on each other during the dry-run, so the
dry-run was removed.
