  9. [lucet-runtime-internals] use custom stack size on FreeBSD, use cfg-if 

    On FreeBSD/amd64, SIGSTKSZ == MINSIGSTKSZ(4 * 512) + 32768 == 34816.
This is not a multiple of the 4k page size, which is required, so use the custom size.

Plus, rewrite the choice using cfg_if, as manual cfgs are getting unwieldy.
