scripts/Makefile.lib: add -L option to LD command for EFI binaries

The linker uses the path specified with -L to search for linker scripts
and for linker script includes.

For out-of-tree builds specify the build directory with -L instead of
the absolute path of the linker script. This allows using an INCLUDE
statement.
