patch 9.1.0827: CI: tests can be improved

Problem:  CI: tests can be improved
Solution: collect failed indent tests, raise timeout for search()
          functions when using ASAN/Valgrind (Aliaksei Budavei)

ASan-instrumented Vim builds tend to run slower (x2) than
non-instrumented Vim builds and occasionally make indent
tests fail when "search*()" functions time out and give up
further execution.
