Fix wpt tests on gcc-6-3 and clang-3-9 builds (#3131)

The timeout value is around the same as web platform test time out
value. In most builds, it will trigger wpt timeout first, and
everything works expected. For gcc and clang builds, these three tests
trigger taskEnvironment timeout first. Slightly
increase the timeout value for taskEnvironment or decrease the timeout
value for wpt seems resolve the issue.
