Move InfoMapTest to extensions_unittests

Move InfoMapTest to extensions_unittests

extensions::InfoMap lives in src/extensions, so run its test suite as part of extensions_unittests.

Two tests are left in Chrome's unit_tests because they depends on the "notifications" permission being available to hosted apps.

BUG=397164
TEST=unit_tests ChromeInfoMapTest, extensions_unittests InfoMapTest

yoz, PTAL.

I'll send out my change to TestExtensionsClient (to add permissions features)
separately, as it isn't required for these tests.
