btrfs-progs: build: omit unnecessary -MD flag

According to gcc(1), "-MD is equivalent to -M -MF file, except that -E is not
implied." Since the rule in the Makefile is just generating dependency file
and not building object file, it is no use to have "-MD" here. Also, it's
overridden and conflicting with the following "-MM" flag. I guess we can drop
it.
