gobject-introspection: replace prelink-rtld with objdump -p

g-i internally processes the output with regexes, and seems
happy with what objdump is printing. It only needs to resolve
the library name as passed to the linker to the library file name.
Also recursive resolution (that ldd is doing and objdump is not)
is not necessary.

-Subject: [PATCH] giscanner: ignore error return codes from ldd-wrapper
-
-prelink-rtld, which we use instead of ldd returns 127 when it can't find a library.
-It is not an error per se, but it breaks subprocess.check_output().
-
-Upstream-Status: Inappropriate [oe-core specific]
