util/nvmutil: move xpledge/xunveil to nvmutil.h

They don't precisely *pertain* to nvmutil, but they are
useful helper functions for calling pledge/unveil in
OpenBSD. Ideally, the main file should only contain core
logic pertaining to the execution of *nvmutil*.

Put xpledge() and xunveil() in nvmutil.h.
