Make allow_system_table_mods settable at run time

Browse Source 
Make allow_system_table_mods settable at run time by superusers.  It
was previously postmaster start only.

We don't want to make system catalog DDL wide-open, but there are
occasionally useful things to do like setting reloptions or statistics
on a busy system table, and blocking those doesn't help anyone.  Also,
this enables the possibility of writing a test suite for this setting.
