include/crypto: Include qapi-types.h or qemu/bswap.h instead of qemu-common.h

qemu-common.h should only be included by .c files.  Its file comment
explains why: "No header file should depend on qemu-common.h, as this
would easily lead to circular header dependencies."

Several include/crypto/ headers include qemu-common.h, but either need
just qapi-types.h from it, or qemu/bswap.h, or nothing at all.  Replace or
drop the include accordingly.  tests/test-crypto-secret.c now misses
qemu/module.h, so include it there.
