Remove vestigial uu_open_tmp(). The problems with this implementation are many, but the primary one is the TMPPATHFMT macro, which is unused, and always has been. Searching around for any users leads only to earlier imports of the same, identical file, i.a. into an apple repository (which does patch gethrtime() into it and gives us a copyright date of 2007), and a MidnightBSD one from 2008. Searching illumos-gate, uu_open_tmp appears, in current HEAD, three times: in the header, libuutil's mapfile ABI, and the implementation. This slowly grows up to eight occurrences as one moves back to the root "OpenSolaris Launch" commit: the header, implementation, twice in libuutil's spec ABI, twice (with multilib and non-multilib paths) in libuutil.so's i386 and SPARC binary db ABIs. That's 2005, and this file was abandonware even then, it's dead code. The situation is similar for the uu_dprintf() family of functions and uu_dump(). Nothing in accessibly recorded history has ever used them. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #11873
