meson: Use dependency() instead of find_library() where possible

Browse source 
Usage of find_library() to find dependencies that libcamera needs to
compile against can lead to the library being found even if the
corresponding headers are not installed. This will then result in a
compilation failure. Switch to dependency() for libdw, libunwind and
lttng-ust to fix this, all three libraries come with a pkgconfig file
that is usually installed by the distribution package that contains the
library headers.
