[pull request] nfs-utils: fixup detection of libtirpc

["Yann E. MORIN" <yann.morin.1998@free.fr>]

Hello All!

This series is an ateempt to fix up the detection of libtirpc.

Since commit 8534063 (configure: use pkg-config to find libtirpc) (by me),
some users are reporting that they can no longer build nfs-utils on older
libtirpc versions.

Furthermore, after inspecting my own change, I saw thatI borked some of
the tests: incorrect test when libtirpc is not required, and dropped
check for authgss_free_private_data.

This series attempts to fix all those issues. Sorry for the mishap...

Regards,
Yann E. MORIN.
