Clean up c-apps Makefile.am and make everything load cleanly again

Executable programs don't have library versions, so don't set -version-info
for them.

Add -version-info to liboils_idl and liboils_util, and link liboils_util
explicitly against liboils_idl rather than relying on AM_LDFLAGS.

Set the linking dependencies correctly; if a library links against
liboils_util, set that as the sole link dependency; no need for liboils_idl
once (let alone twice!)
