Refactor virLockManagerPluginNew() so that the caller does
not need to pass in the config file path itself - just the
config directory and driver name.
Fix QEMU to actually pass in a config file when creating the
default lock manager plugin, rather than NULL.

This makes for some long lines; is it worth wrapping at the ',' now that
you are using a longer name? Or maybe worth declaring:
const char *base = qemu_driver->configBaseDir;
to avoid having to touch these lines?
