We don't need any of these includes in the ctree.h header file for the
header file itself, remove them to clean up ctree.h a little bit.

While the include reduction is nice, we still don't have the includes
for everything ctree.h uses, e.g. spinlock_t, mutex, pid_t, rb_tree and
maybe more. It's not critical as long as it compiles and we have the
includes entangled too much so incremental updates work better. The tool
include-what-you-use can print the recommendeations for adding and
removing includes but it can get confused by direct includes by command
line -include. I did a pass for btrfs-progs, desiable for kernel too.
