tests: ignore the return code of chmod in test-inherit-mode In freebsd, a newly created directory has the same group as the parent directory by default. That means that the test directory created by test-inherit-mode.t is owned by root's group, so "chmod g+s .hg/store" fails to set the SGID bit and returns 1. If we ignore chmod's return code, the testsuite passes again.
