[oe] [PATCH v2] netcat-openbsd: fix implicit dependency on pkg-config

[Paul Gortmaker]

In the report at http://errors.yoctoproject.org/Errors/Details/130673/
we see the following:

i586-oe-linux-gcc  -m32 -march=i586 <snip> netcat.o atomicio.o socks.o `pkg-config --libs libbsd` -lresolv -o nc
/bin/sh: 1: pkg-config: not found

What follows is a bunch of link errors for BSD library functions, as
the backtick didn't return anything but an empty string and hence no
BSD library was involved in the link.

I was able to reproduce this by temporarily removing my host version
of pkg-config, and then validated that this fix solves it while still
having the host binary removed.  So it should fix the reported issue.
I also confirmed pkg-config was in the sysroot after the change.

[v2: use inherit pkgconfig vs. depending on it, as per what
 Khem suggested as being the more conventional route. ]
