[PATCH] meson: wire up USE_NSEC build knob

[PATCH] meson: wire up USE_NSEC build knob

[D. Ben Knoble]

Autotools-style builds permit enabling USE_NSEC for cases where that's
desired; the equivalent knob is missing from meson-based builds.

With or without autoconf, Makefile based build can use USE_NSEC.  It
is a welcome addition to the other side of thw world.  I do not know
if 'meson setup -Dnanosec=true' is a name that is easy to discover,
though.

Will queue.  Thanks.
