xclip-copyfile: mktemp -t option

[nunotexbsd]

Hello,

FreeBSD port needs a patch so xclip-copyfile works correctly:

-archive=mktemp || exit 1
+archive=mktemp -t xclip || exit 1

Could this be included upstream?

"If the -t prefix option is given, mktemp will generate a template string
based on the prefix and the TMPDIR environment variable if set. The
default location if TMPDIR is not set is /tmp. Care should be taken to
ensure that it is appropriate to use an environment variable potentially
supplied by the user."

Thanks,

Nuno Teixeira

I think this change will not affect other operating systems and it should improve portability.
