configure: remove unneeded bits around libunwind handling

If libunwind is not found we'll fail at PKG_CHECK_MODULES, so the
follow-up check will be false. Additionally the AM_CONDITIONAL is not
used, so we can drop it.

Fixes: 3bcef6aa245 ("configure.ac: honour --disable-libunwind if the .pc file is present")
