README: Document dependencies for backtrace generation
libcamera now has the ability to use libdw and libunwind to generate backtraces, in addition to the glibc backtrace() function. libdw provides the most detailed output and is highly recommended, but is limited to parsing backtraces, it doesn't support capturing them. libunwind and backtrace() provide both features. If backtrace() is available, libunwind will not bring any improvement.
