Update tmpfile() existence detection
Linux changed the tmpfile() signature again in torvalds/linux@6521f89, which in turn broke our HAVE_TMPFILE detection in configure. Update that macro to include the new case, and change the signature of zpl_tmpfile as appropriate. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Rich Ercolani <[email protected]> Closes: #12060 Closes: #12087
