This change updates the AC_LANG_PROGRAM autoconf macro invocations to be
wrapped in quotes. As of autoconf version 2.68, the quotes are necessary
to prevent warnings from appearing. Specifically, the autoconf v2.68
Forward Porting Notes specifies:
It is important to note that you need to ensure that the call to
AC_LANG_SOURCE is quoted and not expanded, otherwise that will
cause the warning to appear nonetheless.
Finally, because of the additional quoting we can drop the extra
quotas used by the ZFS_AC_CONFIG_USER_STACK_GUARD autoconf check.
