    Pass link libraries via LIBS variable into Makefiles (#734718)
    
    Currently -lparted is passed to the linker by being hard coded in the
    gpartedbin_LDFLAGS variable in src/Makefile.am and -lparted-fs-resize
    by conditionally being appended to the gpartedbin_LDFLAGS.
    
    Add an Autoconf AC_CHECK_LIB check for the parted library using it's
    default action-if-found to extend LIBS.  Update the existing
    AC_CHECK_LIB check for the parted-fs-resize library so that the
    overridden action-if-found also extends LIBS with -lparted-fs-resize.
    These libraries are then assigned via the LIBS variable in the
    generated Makefiles.
    
    This matches how the other libraries, dl and uuid, were found in the
    configure script and passed to the Makefiles.
    
    Bug #734718 - Update Autoconf version specific libparted checks and
                  defines to feature specific ones
