Host files installed in Build/InstallDev are target-specific and will stay
in $(STAGING_DIR)/host after the STAGING_DIR_HOSTPKG unification.

As both LEDE and OpenWrt have STAGING_DIR_HOSTPKG now, we can start to rely
on it. See 73b7f55424 for more information on
STAGING_DIR_HOSTPKG.

STAGING_DIR_HOSTPKG won't actually be changed before the first LEDE release
(it is equivalent to $(STAGING_DIR)/host), so this simple search/replace
cleanup is safe to apply. Doing this cleanup now will be useful for the
Gluon project (an OpenWrt/LEDE based firmware framework) for experimenting
with modifying STAGING_DIR_HOSTPKG before doing this in the LEDE upstream.

Also fixes a typo in the dbus Makefile ("STAGIND_DIR").

Call the cpp preprocessor with -P argument which is now needed by gcc-5.
