oeqa/selftest: add test for git working correctly inside pseudo

Browse Source 
The fix for CVE-2022-24765 in git[1] breaks any use of git inside
pseudo. Add a simple test case to oe-selftest to verify that at least
basic uses of git work fine under pseudo.

Git binaries with CVE-2022-24765 fixed will refuse to operate on a
repository which is owned by a different user. This breaks our
do_install task as that runs inside pseudo, so the git repository is
owned by the build user but git is running as (fake)root.
We have an intercept which disables pseudo, so verify that it works.
