[psaux] Revise `PS_Table` handling.

The old impleemntation was not using `FT_REALLOC`, buing too careful
with the offset rebasing.  It shoudl be safe to rely on the base
movements.

* src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine
into...
(ps_table_realloc): ... this function based on `FT_REALLOC`.
(ps_table_done): Simplified.
(ps_table_add): Updated.
