cirrus-ci: install libinotify for FreeBSD

FreeBSD QEMU build requires libinotify, otherwise the build fails with:

./qemu-xen-dir-remote/meson.build:2535:15: ERROR: C shared or static library 'inotify' not found

Install the package and add the /usr/local include and libs paths
explicitly as QEMU configure options.
