test lib: change "error" to "BUG" as appropriate

Change two uses of "error" in test-lib-functions.sh to "BUG". In the first instance in "test_cmp_rev" the author of the "BUG" function added in [1] had another in-flight patch adding this in [2], and the two were never consolidated. In the second case in "test_atexit" added in [3] that we could have instead used "BUG" appears to have been missed. 1. 165293af3ce (tests: send "bug in the test script" errors to the script's stderr, 2018-11-19) 2. 30d0b6dccbc (test-lib-functions: make 'test_cmp_rev' more informative on failure, 2018-11-19) 3. 900721e15c4 (test-lib: introduce 'test_atexit', 2019-03-13) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
