Revert "Decompress a .ffpfsc on the console (#453)"

This reverts commit 1f27c1a560.

Every helper build that linked the vendored zlib died within minutes on a
FW 13.60 Phat with SIGBUS in a system library touching helper code at
zlib's inflateEnd (logged by the new fault detail: addr=0x200161159,
rip=0x88007fe60), most often right after an app kill. One such build was
running when the console went down during a game launch and did not come
back. The same helper without zlib ran through repeated launches and kills.
The decompress op goes back out until it can run without linking zlib into
the helper.
