Remove duplicate files from ${ALLFILES}. This doesn't affect the

"fetch" target, but it does affect the "checksum" target's shell
script, which errors out on the second occurrence of a file. The
shell script should perhaps also be fixed, but it seems sensible
regardless for ${ALLFILES} not to contain duplicate filenames. As
a side effect, the file list is sorted.

Regression found by building mail/qmail with the "qmail-netqmail"
option, which adds to PATCHFILES a file that's already in ${DISTFILES}.
Arguably this is gross, but it worked before, and now works again.

Tested on my usual pkg_comp(8) build of 200+ packages, with an
initially empty ${DISTDIR} and ${PACKAGES}. Thanks seb@ for the
more idiomatic make(1) construction.
