Subject: [PATCH] Update GUC setting to not crash with ASAN (#8301)

The GUC configuration for SkipAdvisoryLockPermissionChecks had
misconfigured the settings for GUC_SUPERUSER_ONLY for PGC_SUSET - when
PostgreSQL running with ASAN, this fails when querying pg_settings due
to exceeding the size of the array GucContext_Names. Fix up this GUC
declaration to not crash with ASAN.
