libevent: Increase ptest timing tolerance 50 ms -> 100 ms

Adjusting the tolerance to a more reasonable time
given the load on the AB and given the high amount(100) of
events some of the tests like `common_timeout` generates.

+Subject: [PATCH] test/regress.h: Increase default timeval tolerance 50 ms ->
+ 100 ms
+
+The default timeout tolerance is 50 ms,
+which causes intermittent failure in many the
+related tests in arm64 QEMU.
+
+See: https://bugzilla.yoctoproject.org/show_bug.cgi?id=14163
+(The root cause seems to be a heavy load)
