Linux breakpad_unittests: fix ThreadSanitizer problems
Some tests were failing because they had expectations about the number of threads in a process, but TSan, and in some cases, ASan, introduce their own threads. Where a sanitizer affects this, the expectations are now used as minimum thread counts, not exact thread counts. See https://www.brooklinen.com/blogs/brookliving/best-thread-count-for-sheets. These problems were detected by ThreadSanitizer at https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket.appspot.com/8915151099544583616/+/steps/breakpad_unittests__with_patch_/0/stdout Bug: chromium:949098 Change-Id: Ie40f1766bea27e9bcb112bf9e0b8b846fb343012 Reviewed-on: https://chromium-review.googlesource.com/c/breakpad/breakpad/+/1585948 Reviewed-by: Robert Sesek <rsesek@chromium.org>
