unix: fix sock-opt test case.

On systems with true Unix heritage, like Solaris,
MacOS/Darwin, and undoubtedly various BSDs, getsockopt is
returning a bitmask value for some options , rather than 1.
For instance if we enable SO_REUSEADDR, and then read back the
value of the option, we get 4 and not 1. This is because the
value of the SO_REUSEADDR symbol itself is 4; it is a mask.
The kernel code is evidently just masking out the desired
option out of the option mask, and returning the mask value
without reducing it to 0 or 1.

* tests/014/socket-misc.tl: Test the result of sock-opt for
nonzero using nzerop rather than testing specifically for 1.
