log test: skip a failing mkstemp() test under valgrind

Skip a test added in f1e3df31699 (t: increase test coverage of signature verification output, 2020-03-04) when running under valgrind. Due to valgrind's interception of mkstemp() this test will fail with: + pwd + TMPDIR=[...]/t/trash directory.t4202-log/bogus git log --show-signature -n1 plain-fail ==7696== VG_(mkstemp): failed to create temp file: [...]/t/trash directory.t4202-log/bogus/valgrind_proc_7696_cmdline_d545ddcf [... 10 more similar lines omitted ..] valgrind: Startup or configuration error: valgrind: Can't create client cmdline file in [...]/t/trash directory.t4202-log/bogus/valgrind_proc_7696_cmdline_6e542d1d valgrind: Unable to start up properly.
