debian: 3.49.10-2, fix buildd FTBFS via quilt patch

3.49.10-1 failed to build on every Debian buildd: tests/28_local-pause
failed instead of skipping when python3 is absent (the local-server tests
need python3, which the minimal buildd chroot lacks). The fix is already
upstream, but the -1 orig is frozen in the archive, so carry it as a quilt
patch and bump to -2. Packaging-only; no upstream code change.

+Description: skip 28_local-pause when python3 is absent (fixes FTBFS on buildds)
+ The local-server tests skip (exit 77) when python3 is missing, but
+ 28_local-pause wrapped local-crawl.sh in a command substitution that swallowed
+ that skip. On the python3-less buildd chroot the test then ran serverless, both
+ crawls finished in 0s, and the 0s delta was reported as a failure. Guard the
+ test on python3 up front, like its siblings, so it skips cleanly.
