After OpenWrt base updated WolfSSL to version 5.6.3, the strongswan wolfssl
plugin fails to compile due to a header conflict.
The error reported by the builders is:
In file included from .../usr/include/wolfssl/openssl/asn1.h:27,
from .../usr/include/wolfssl/ssl.h:4123,
from wolfssl_common.h:64,
from wolfssl_ec_private_key.c:23:
../../../../src/libstrongswan/asn1/asn1.h:43:9: error: 'WOLFSSL_ASN1_STRING' redeclared as different kind of symbol

make[9]: *** [Makefile:621: wolfssl_ec_private_key.lo] Error 1
Solve this issue by adding a local path that remaps `ASN1_UTF8STRING`
during wolfssl header inclusion, like it is done already for other
conflicting defines.
