[PS4/PS5][Driver] Observe <sysroot>/target/lib for libraries (llvm#123350)
On PS5, if a custom --sysroot is supplied, `<sysroot>/target/lib` should be added to the library search paths (this already occurs if the default `--sysroot` is not overridden). Until now, this has been hardcoded as a downstream patch in lld. Add it to the driver so that the private patch can be removed. On PS4 the library search paths remain unchanged. The proprietary linker will continue to handle this aspect. On either platform, warn if `<sysroot>/target/lib` is absent. Previously, such warnings were emitted only when the default --sysroot was not overridden. SIE tracker: TOOLCHAIN-16704
