crypto: crc32 - remove "generic" from file and module names

Since crc32_generic.c and crc32c_generic.c now expose both the generic
and architecture-optimized implementations via the crypto_shash API,
rather than just the generic implementations as they originally did,
remove the "generic" part of the filenames and module names:

    crypto/crc32-generic.c => crypto/crc32.c
    crypto/crc32c-generic.c => crypto/crc32c.c
    crc32-generic.ko => crc32-cryptoapi.ko
    crc32c-generic.ko => crc32c-cryptoapi.ko

The reason for adding the -cryptoapi suffixes to the module names is to
avoid a module name collision with crc32.ko which is the library API.

We could instead rename the library module to libcrc32.ko.  However,
while lib/crypto/ uses that convention, the rest of lib/ doesn't.  Since
the library API is the primary API for CRC-32, I'd like to keep the
unsuffixed name for it and make the Crypto API modules use a suffix.
