package/pipewire: bump version to 1.6.6

Release notes:
https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/1.6.6/NEWS

ffmpeg support needs swscale support:
2cbcdbc579

Renamed configure option 'systemd' to 'libsystemd' due to commit
f2c878a2c1

Disabled jack2 support for uClibc to fix a build error:

../pipewire-jack/src/pipewire-jack.c:13:10: fatal error: threads.h: No such file or directory
   13 | #include <threads.h>

Removing this include will not fix the problem:

../pipewire-jack/src/pipewire-jack.c:127:20: error: expected ‘;’ before ‘float’
  127 | static thread_local float midi_scratch[MIDI_SCRATCH_FRAMES];

Fixes:
