Makefile,meson.build: Fix dependency issues with raiden_debug_spi

The Raiden debug external spi programmer need only depend
on libusb and is unrelated to libpci. Correct meson and gnu make
builds where meson had configuration in the incorrect section
and gnu make artifactually disabled the build on Windows/MinGW
which doesn't have libpci.

BUG=none
TEST=still continues to build.
