[Devel] liblxc: Add pkg-config file

[Matt Helsley]

Add a pkg-config file which makes developing with liblxc easier. For
example, if an unusual --prefix is used to install liblxc no special
changes to Makefile rules are needed if pkg-config is used:

        gcc $(shell pkg-config --cflags) $(shell pkg-config --libs) -o my_lxc_prog my_lxc_prog.c
