David Turner d0ab058498 tests: remove some direct access to .git/logs
Alternate refs backends might store reflogs somewhere other than
.git/logs.  Change most test code that directly accesses .git/logs to
instead use git reflog commands.

There are still a few tests which need direct access to reflogs: to
check reflog permissions, to manually create reflogs from scratch, to
save/restore reflogs, to check the format of raw reflog data, and to
remove not just reflog contents, but the reflogs themselves. All cases
which don't need direct access have been modified.

# which catches glibc (with an 8K BUFSIZ) and *BSD (1K).

# Each line is 114 characters, so we need 75 to still have a few before the
