Loop when necessary in contrib/pgcrypto's pktreader_pull().
This fixes a scenario in which pgp_sym_decrypt() failed with "Wrong key
or corrupt data" on messages whose length is 6 less than a power of 2.
Per bug #11905 from Connor Penhale. Fix by Marko Tiikkaja, regression
test case from Jeff Janes.
