Consider the bare repository called "mirror" in the test. Running `git
remote add --mirror -f origin ../one` will not change HEAD, consequently
if init.defaultBranch is not the same as what HEAD in the remote
("one"), HEAD in "mirror" will be pointing to a non-existent reference.
Hence if "mirror" is used as a remote by yet another repository,
ls-remote will not show HEAD. On the other hand, if init.defaultBranch
happens to match HEAD in "one", then ls-remote will show HEAD.

Since the "ci/run-build-and-tests.sh" script globally exports
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main for some (but not all) jobs,
there may be a drift in some tests between how the test repositories are
set up in the CI and during local testing, if the test itself uses
"master" as default instead of "main". In particular, this happens in
t5505-remote.sh. This issue does not manifest currently, as the test
does not do any remote HEAD manipulation where this would come up, but
should such things be added, a locally passing test would break the CI
and vice-versa.

Set GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main in t5505-remote to be
consistent with the CI.

          see
          https://lore.kernel.org/git/D4ZAELFWJMKN.S88LJ6YK31LZ@ferdinandy.com/ for the root cause in detail
    
    v10: no change
    
    v11: no change
    
    v12: added forgotten sign-off
    
    v13: commit message udpated to be more precise
    
    v14: made explicit in the commit message that the default branch is only
         set for some CI jobs
