In order to allow using utimensat() in install(1), add futimens() and utimensat() to -legacy. The files futimens.c and utimensat.c are modified copies of the files under lib/libc/sys/ since the libc versions use symbols that do not exist in the libc on the build system (sys_futimens and sys_utimensat) . I expect the next non-sweeping change to both sets of files to be to delete them, anyway. This will allow reverting r299942 (which is a revert of r299850) enabling nanosecond timestamps in install(1). Reviewed by: bdrewery
