wolfssl: add libwolfssl-cpu-crypto package
libwolfssl-cpu-crypto is a variant of libwolfssl with support for
cryptographic CPU instructions on x86_64 and aarch64.
On aarch64, wolfSSL does not perform run-time detection, so the library
will crash when the AES functions are called. A preinst script attempts
to check for support by querying /proc/cpuinfo, if installed in a
running system. When building an image, the script will check the
DISTRIB_TARGET value in /etc/openwrt_release, and will abort
installation if target is bcm27xx.
