lib/sysfs: Avoid using FILE* temporary for igt_sysfs_[v]printf

Currently we wrap our fd inside a FILE* stream to make use of vfprintf,
but the man page leaves the question of errno and signal handling in
doubt. It is documented as returning a negative value and setting
ferror(), but we have been interpreting errno to handle signal
restarting. As that is in doubt, reduce it to a sprintf and reuse our
common interrupt handling write() that already returns -errno.
