Implement ScopedFD in terms of ScopedGeneric.

Move to a new file base/files/scoped_file.h. I will also add ScopedFILE to here (currently in file_util.h) later.

I think there is a crash in the old code in content/browser/zygote_host/zygote_host_impl_linux.cc that this patch should fix. The old ScopedFD took the address of something in a vector that is being modified.

I removed SafeScopedFD from content/common/sandbox_linux/sandbox_linux.cc since base's ScopedFD not CHECKs on close failure (this is a more recent addition).
