Pull flockfile/funlockfile/ftrylockfile into stdio.cpp.

These are just one-liners, and the _FLOCK() macro seemed to me more
obscure than just inlining it (especially because there are only four
call sites total, so it's not like anyone's going to see that macro very
often).

Also add the missing CHECK_FP() calls. I don't expect this to break
anything, but if it does we can add a target API level check.
