crypto: pcomp - Fix illegal Kconfig configuration

The PCOMP Kconfig entry current allows the following combination
which is illegal:

ZLIB=y
PCOMP=y
ALGAPI=m
ALGAPI2=y
MANAGER=m
MANAGER2=m

This patch fixes this by adding PCOMP2 so that PCOMP can select
ALGAPI to propagate the setting to MANAGER2.
