vendor.sh: optimise find_me()

i'm adding characters to 7ztest, which isn't being passed
on through because everything runs in subshells; the next
pass would default back to the original string, so a given
file may be checked multiple times.

fix this by mitigation; use the random string from mktemp
as a suffix instead.

in practice, this has not affected performance much, but it
will nevertheless avoid unnecessary work by xbmk.
