When running tests on a remote device, framework convenience symlinks
created by test Makefiles (e.g. `$(BUILDDIR)/Framework` pointing to
`$(BUILDDIR)/Framework.framework/Framework`) cause launch failures.
`Platform::Install` recreates these as symlinks on the remote device
pointing to host build paths that don't exist, resulting in "No such
file or directory" from dyld.
This patch changes `LN_SF` in Makefile.rules to strip the common
directory prefix from the symlink source using `patsubst` so it produces
relative symlinks instead of absolute ones.
It also resolve symlinks with `os.path.realpath()` in
`registerSharedLibrariesWithTarget` before registering modules so that
`Platform::Install` sees a regular file and transfers the actual binary
content.
