fixpatch: projectm 3.1.12

This PR should fix dpf-plugins building fault: https://archriscv.felixc.at/.status/log.htm?url=logs/dpf-plugins/dpf-plugins-1.7-2.log , although projectm itself can be built successfully with current riscv64 patch.

The current PR use autoreconf to update the outdated config.{guess,sub} , while also updating libtool at the same time, which breaking the behavior of sed -i -e 's/ -shared / -Wl,-O1,--as-needed\0/g' libtool in the original PKGBUILD, which causes projectm to be overlinked, more specifically linking libprojectm.so to libqt5gui.so and libqt5opengl.so, meanwhile projectm's depends not containing qt5-base.

Although, the dpf-plugins doesn't depend on qt5-base, then, boom.
