[PATCH] t/perf: rename duplicate-numbered test script

There are two perf scripts numbered p5600, but with otherwise different names ("clone-reference" versus "partial-clone"). We store timing results in files named after the whole script, so internally we don't get confused between the two. But "aggregate.perl" just prints the test number for each result, giving multiple entries for "5600.3". It also makes it impossible to skip one test but not the other with GIT_SKIP_TESTS.

Let's renumber the one that appeared later (by date -- the source of the problem is that the two were developed on independent branches). For the non-perf test suite, our test-lint rule would have complained about this when the two were merged, but t/perf never learned that trick.

This is meant for 2.23, but obviously it's not hurting anything if it
doesn't make the cut. I double-checked that there is no conflict with
anything on pu, either. :)

In other news, I ran the whole perf suite on v2.23.0-rc2, and there was nothing interesting aside from the expected improvement from 39b44ba771 (check_everything_connected: assume alternate ref tips are valid, 2019-07-01).
