Title: make: build common/secret only on linux

libkeyutils is only available on linux. before the automake refactoring
secret.c was compiled into rbd and ceph_mount targets which are linux
only targets. secret.c was moved to libcommon during the refactoring,
but the conditional compilation was lost.
