update to 2.39.0-rc0

Add mod_http2 BuildRequires for t5559-http-fetch-smart-http2; skip it on
EL7, which lacks it.  Ignore the expected 'missing HTTP2' output from
t5551-http-fetch-smart.  Use a strict pattern to avoid unintended
matches.

Sadly, we must also disable t5559 for now.  It fails very often across
all architectures.  The most common failure is "large fetch-pack
requests can be sent using chunked encoding" (t5559.30), but earlier
tests have also failed.  Until these failures are understood and
resolved, the entire test is disabled globally.  (It's also disabled for
EL-7, which is redundant now but won't be after we re-enable the test
globally in the near future.)

We can't simply skip the mod_http2 dependency here because we set
GIT_TEST_HTTPD=true.  Per upstream 73c49a4474 (t: run t5551 tests with
both HTTP and HTTP/2, 2022-11-11):

    If HTTP/2 isn't supported on a given platform, then t5559 should
    bail during the webserver setup, and gracefully skip all tests
    (unless GIT_TEST_HTTPD has been changed from "auto" to "yes", where
    the point is to complain when webserver setup fails).

Also ignore the 'missing BUILTIN_TXT_$builtin' output which comes from
upstream a0c3244796 (doc SYNOPSIS & -h: use "-" to separate words in
labels, not "_", 2022-10-13).  We may want to loosen this in the future,
but for now ignore it because it doesn't help us identify missing test
dependencies.
