Fix detection of ARMv7 and ARM64 CPU features on FreeBSD

OpenSSL assumes AT_HWCAP = 16 (as on Linux), but on FreeBSD AT_HWCAP = 25
Switch to using AT_HWCAP, and setting it to 16 if it is not defined.

OpenSSL calls elf_auxv_info() with AT_CANARY which returns ENOENT
resulting in all ARM acceleration features being disabled.
