m4/virt-gnutls: use AC_CHECK_FUNCS to detect availability of functions

Sigh, autoconf has AC_CHECK_FUNC and AC_CHECK_FUNCS and both check
whether some function exists or not.  However in addition to the obvious
difference that the later is able to check multiple functions it also
defines HAVE_FUNCTION_NAME for each function.

Commit 680d2f49da moved the code to separate file, but also blindly
changed the macro to AC_CHECK_FUNC without confronting the
documentation.
