nss: Pass NSS_USE_ARM_HW_CRYPTO as define in CFLAGS

Use NSS_USE_ARM_HW_CRYPTO to detect USE_ARM_GCM, since there are
dependent, without this we control the crypto code function inclusion in
build but do not control the call sites, which can result in undefined
symbols e.g.

Linux_SINGLE_SHLIB/gcm.o: in function `gcmHash_InitContext':
/usr/src/debug/nss/3.49.1-r0/nss-3.49.1/nss/lib/freebl/gcm.c:112: undefined reference to `gcm_HashInit_hw'
