The patch for CVE-2018-19840 was already upstreamed in 5.2.0, but
patch(1) helpfully still applied it which results in (harmlessly)
checking the same condition twice.

Also add options=!check since the test suite wasn't being run anyway -
it requires tcl (which is a circular dependency :/) and is in the "src"
distribution, not the "autoconf" one.

Also remove obsolete CVE-2017-7867-7868.patch - this was merged since at
least 59.1 and was left over from when icu was originally pulled into the
system/ tree in 2018.
