Subject: [PATCH] tests: mark performance-related tests as expensive

These performance-related tests are slightly failure prone due to
varying system load during the two runs.
Marking these tests as "expensive" makes it so they are no longer run
via "make check". You can still run them via make "check-expensive".
This makes them less likely to be run by regular users.
* tests/long-pattern-perf: Use expensive_.
* tests/mb-non-UTF8-performance: Likewise.
