Subject: [PATCH] folly/FileUtil.h: fix compiler warning signed/unsigned
 comparison

Summary:
writeFull() returns ssize_t and without proper casting, comparing
it with data.size() triggers a compiler warning (which is
treated as an error) in the gcc-4.9-glibc-2.20 toolchain.

Test Plan: fbmake runtests
