Cannot build on arch-based distros.

[matekelemen]

The system pulse detector script cannot strip commit hashes from the version string, which leads to the pulse download script failing (cannot find a suitable pulse version to download).

roc-pulse/cmake/detect_system_pulseaudio_version.cmake

Line 2 in 0750cc3

COMMAND sh -c "pulseaudio --version | sed -e 's,^[^0-9]*,,'"

This is a problem on arch-based distros (I'm on manjaro) because the current pulseaudio version is pulseaudio 17.0-43-g3e2bb.

I guess the the detector should provide 17.0, because that's what's available on freedesktop, but it detects 17.0-43-g3e2bb instead.

Manually passing -DPULSEAUDIO_VERSION=17.0 to cmake will get the build done, but the install directory gets incorrectly set to /usr/local/lib/pulse-17.0/modules/ somewhere instead of /usr/lib/pulseaudio/modules, so pulse cannot find the installed modules.
