Git 2.30.0 and failed self tests

[Jeffrey Walton <noloader@xxxxxxxxx>]

Hi Everyone,

I'm seeing some failed self tests with 2.30.0 on Fedora 33 x86_64
fully patched. They seem to be centered around email.

    *** t9001-send-email.sh ***
    ok 1 - prepare reference tree
    ok 2 - Setup helper tool
    ok 3 - Extract patches
    not ok 4 - No confirm with --suppress-cc
    #
    #        test_no_confirm --suppress-cc=sob &&
    #        check_no_confirm
    #
    ...

    not ok 174 - test forbidSendmailVariables behavior override
    #
    #        test_config sendmail.program sendmail &&
    #        test_config sendemail.forbidSendmailVariables false &&
    #        git send-email \
    #            --from="Example <nobody@xxxxxxxxxxx>" \
    #            --to=nobody@xxxxxxxxxxx \
    #            --smtp-server="$(pwd)/fake.sendmail" \
    #            HEAD^
    #
    # failed 132 among 174 test(s)
