virtlogd: Fix build without DBus

The rule for virrotatingfiletest was defined in DBUS-only block even
though the test does not use DBus at all.  Also DBUS_CFLAGS and
DBUS_LIBS are removed from the rules.  The original error was:

/usr/lib/gcc/x86_64-pc-linux-gnu/5.2.0/../../../../lib64/Scrt1.o: In
function `_start':
(.text+0x20): undefined reference to `main'
