Reenable Win 7 DevToolsReattachAfterCrashTest

DevToolsReattachAfterCrashTest was disabled on Windows 7 because loading
of debug information was too slow and caused timeouts. This was caused
by symbol_level=1 becoming more verbose (including line numbers and
source files) and dbghelp.dll on Windows 7 seems to be particularly
inefficient. This was fixed a while ago by getting the bots to default
to symbol_level=1. This is the first of a few changes to reenable the
tests that were disabled.
