It has to set T, because that is how t/Makefile knows what the set of
tests is. The problem is that test-lint-duplicates does not understand
absolute pathnames, as its regex is too simplistic:

  sed 's/-.*//' | sort | uniq -d

So it finds whatever is before the first "-", which would be the test
number in "t0000-basic.sh" or similar, and then looks for duplicates.

We can make the regex more strict to handle full paths, like:

  perl -lne 'print $1 if m{(?:^|/)(t\d{4})-}'

but that still would not help, as the tests in remote-helpers do not
follow the tXXXX convention. So I think even running
test-lint-duplicates on them is nonsensical.

Maybe something like this would be more appropriate, though it kills off
all test-lint checks, not just test-lint-duplicates:
