crda: check the word size of target instead of host machine.

Issue: LIN8-5177

When 'USE_OPENSSL=1' is configured for crda, key2pub.py doesn't
create "keys-ssl.c" with target's word size. Pass 'SITEINFO_BITS'
from building system to key2pub.py.

+Subject: [PATCH] crda: fix issues when 'USE_OPENSSL=1'.
+
+Fxed the below issues if configured with 'USE_OPENSSL=1':
+a. keys-ssl.c uses BN_ULONG but doesn't include the openssl headers leading
+   to build failures:
+   keys-ssl.c:2:8: error: unknown type name 'BN_ULONG'
+   static BN_ULONG e_0[1] = {
+
+b. The large unqualified constants also break building:
+   keys-ssl.c:8:2: warning: overflow in implicit constant conversion [-Woverflow]
+     0x63a2705416a0d8e1, 0xdc9fca11c8ba757b,
+
+c. keys-ssl.c: error: 'keys' defined but not used [-Werror=unused-variable]
+   static struct pubkey keys[] = {

+Subject: [PATCH] crda: Use target word size instead of host's.
+
+In key2pub.py, the codes check the wordsize
+of the host machine but not the target's, this fix
+fetches the wordsize of target from the build system.
