[OE-core] [PATCH 2/2] clutter-gst-3.0: add --enable/disable-gudev

[Robert Yang]

Fix dangling dependns on gudev, and systemd doesn't provide libgudev, so
it can't be enabled when systemd either.

Fixed:
libtool: error: cannot find the library 'tmp/sysroots/qemuarm64/usr/lib64/libgudev-1.0.la' or unhandled argument
'tmp/sysroots/qemuarm64/usr/lib64/libgudev-1.0.la'
