Remove custom memory allocation layer in pgcrypto

Browse Source 
PX_OWN_ALLOC was intended as a way to disable the use of palloc(), and
over the time new palloc() or equivalent calls have been added like in
32984d8, making this extra layer losing its original purpose.  This
simplifies on the way some code paths to use palloc0() rather than
palloc() followed by memset(0).
