app/internal: use pkg-config for finding system headers and libraries

I've resisted relying on pkg-config in the hope that hard-coded include and
library paths would suffice. However, apart from having to work around some
distro-specific differences, building with hardcoded include paths fails when
building on a buildroot:

	x86_64-buildroot-linux-gnu-gcc: ERROR: unsafe header/library path used in cross-compilation: '-I/usr/include/wayland'

(see #91)

Andri mentions a workaround (prefixing paths with "="), but that doesn't seem
to work on the BSDs.

Let's see how pkg-config fares. It's an extra dependency, but it promises to keep
us isolated from the varying paths on Linux distrobutions.

Updates #91
