valgrind-devel @3.14.0-r2017-11-21 +gcc6 +openmpi: intermittent git-checkout failure

[majoc-at-astro (majoc-at-astro)]

Sometimes, but not always, valgrind-devel fails to check out during our periodic nightly builds, then succeeds in a manually-initiated rerun. Logfile enclosed, but here's the top bits:

:debug:fetch system: /usr/bin/git clone --progress http://sourceware.org/git/valgrind.git /opt/local/var/macports/build_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_valgrind/valgrind-devel/work/valgrind-3.14.0-r2017-11-21 2>&1

:info:fetch error: fetch failed.

On investigation, ​http://www.valgrind.org/downloads/repository.html suggests the Portfile is checking out with the wrong URL, which may quite possibly yield timeouts or other breakage. Here's the results of some experiments, pulled from our nightly logs:

    git.url         http://sourceware.org/git/valgrind.git
00:07:40 ### (178 of 961: mp_merged.bash) port fetch valgrind-devel +gcc6 +openmpi (Thu May 24 14:21:30 BST 2018)

    git.url         git://sourceware.org/git/valgrind.git
00:01:14 ### (171 of 954: mp_merged.bash) port fetch valgrind-devel +gcc6 +openmpi (Thu May 24 00:36:29 BST 2018)

    git.url         http://repo.or.cz/valgrind.git
00:00:54 ### (178 of 961: mp_merged.bash) port fetch valgrind-devel +gcc6 +openmpi (Thu May 24 14:24:30 BST 2018)

I enclose the obvious patch for the Portfile for the last of the above, which uses the mirror suggested in ​http://www.valgrind.org/downloads/repository.html .

Please feel free to merge this with #56151. Thanks in advance; apologies (as ever) for errors of markup.

Thank you for the patch! I will switch to this Git mirror in the hope it works better. Although sourceware.org actually also lists this ​http:// URL for the ​valgrind repository.

valgrind-devel: Switch to recommended Git mirror

There have been some reports that the sourceware.org Git repository does
not work reliable over HTTP. Use the Git mirror recommended by the
valgrind website at ​http://www.valgrind.org/downloads/repository.html

See: #56151
Closes: #56532
