main/coreutils: fix mv under fakeroot

coreutils 9.5's mv started to use gnulibs renematu which will use
renameat2 if found or fallback to direct syscall. musl does not
implement renameat2 so gnulib will cal syscall directly and escape
fakeroots interception.

To work around this, disable using the direct syscall and use the
fallback from gnulib for now.
