bitbake: lib/bb: Don't treat mc recipe (Midnight Commander) as a multiconfig target

When we run `devtool build mc` recipe's task dependencies are expanded
to "mc:do_populate_sysroot" where "mc" name is treated as multiconfig
and "do_package_sysroot" as multiconfigname.

| ERROR: Multiconfig dependency mc:do_populate_sysroot depends on
| nonexistent multiconfig configuration named do_populate_sysroot
