[arch-dev-public] [signoff] pciutils 3.1.7-4

[Jan de Groot]

Please signoff for both architectures.

This update cleans up the PKGBUILD in a way that uses all possibilities
that are present in the Makefile:
- PREFIX="$pkgdir/usr" is replaced by using DESTDIR
- install-lib target is used instead of copying files around

This release contains both shared and static libraries. As I don't have
any overview of what still needs this static library (default is to ship
only static), I decided to keep it in for a while. As we're using the
install-lib target, a .pc file is also shipped now.
