Staging: pohmelfs: fix kconfig dependencies

pohmelfs wants to use CONNECTOR, so it selects CONNECTOR,
but when CONFIG_NET is not enabled, connector.c will not build,
since select does not follow the dependency chain.
Selecting NET is not a good idea, since that would build lots
of code that someone seemingly didn't want to build/store
and kconfig shouldn't do that behind someone's back.

pohmelfs should depend on NET since it uses network interfaces.

pohmelfs also uses CRYTPO and selects 2 cipher symbols, but
it should also select the top-level CRYPTO symbol since
kconfig dependency chains are not followed.
(found by inspection)
This allows the POHMELFS_CRYPTO option to depend only on
POHMELFS and makes the kconfig menu align properly.

Also fix minor typos & line lengths in kconfig help text.
Drop CONFIG_* in kconfig symbols in Kconfig file.
