do verification and extraction on memory, not files

Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.

For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.

Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.
