BUG/MINOR: auth: report valid crypto(3) support depending on build options

Since 1.8 with commit e8692b41e ("CLEANUP: auth: use the build options list
to report its support"), crypt(3) is always reported as being supported in
"haproxy -vv" because no test on USE_LIBCRYPT is made anymore when
producing the output.

This reintroduces the distinction between with and without USE_LIBCRYPT
in the output by indicating "yes" or "no". It may be backported as far
as 1.8, though the code differs due to a number of include files cleanups.
