remote: refactor & rename variables for building libvirtd

The same make variables will be useful for building both libvirtd and
the split daemons, so refactor & rename variables to facilitate reuse.

Automake gets annoyed if you define a variable ending LDFLAGS:

src/remote/Makefile.inc.am:53: warning: variable 'REMOTE_DAEMON_LDFLAGS' is defined but no program or
src/remote/Makefile.inc.am:53: library has 'REMOTE_DAEMON' as canonical name (possible typo)

So we trick it by using an LD_FLAGS or LD_ADD suffix instead.
