mips: vdso: Fix flip/flop vdso building bug
Running "make" on an already compiled kernel tree will rebuild the
vdso library even if this has not been modified.
$ make
GEN Makefile

The issue is generated by the fact that "if_changed" is called twice
in a single target.
Fix the build bug merging the two commands into a single function.
