Reference to hard-coded gitattributes path fails if no access

[ian-burnett]

Scenario:

Running on a system where a /data directory exists, but to which the current user has no access.

Running a git command produces the following warning:

MV2C ~/git/cics-perf-common > git status
warning: unable to access '/data/zopen/usr/local/zopen/git/git-v2.49.0/etc/gitattributes': EDC5111I Permission denied.
On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean

If the /data directory does not exist, no warning is produced.

The git index is updated by the above commands, which means the warning is only produced once per repo. Resetting the git index can also produce the same problem:

rm .git/index
bash-5.2$ git reset --hard origin/main
warning: unable to access '/data/zopen/usr/local/zopen/git/git-v2.49.0/etc/gitattributes': EDC5111I Permission denied.
