Tests_DB::test_locale_floats() cannot be tested on Travis

[johnbillion]

The Tests_DB::test_locale_floats() test relies on one of the following locales to be available:

• ru_RU.utf8
• fr_FR.utf8
• de_DE.utf8
• es_ES.utf8

However none of these locales are installed on the environment used by Travis, so the test is skipped. The following locales are available, but they're all English:

• en_AG.utf8
• en_AU.utf8
• en_BW.utf8
• en_CA.utf8
• en_DK.utf8
• en_GB.utf8
• en_HK.utf8
• en_IE.utf8
• en_IN.utf8
• en_NG.utf8
• en_NZ.utf8
• en_PH.utf8
• en_SG.utf8
• en_US.utf8
• en_ZA.utf8
• en_ZM.utf8
• en_ZW.utf8

The test was introduced in #19861.

In 40529:

Build/Test Tools: Partially revert [40524].

See #40533, #40535

Seems like ​installing custom language packs on before_install should work?

Lets see, in a quick hacky patch I added de, es, fr, and ru language pack per Travis CI docs:

Notes: The packages should remain cached as apt packages are already included in the cache config, though it will still install them for the JS only test needlessly slowing this build job down

Only one of the jobs is not erroring, the HHVM job as the apt command isn't available in all Travis CI environemnts

From my quick look at the job the test_locale_floats() test hasn't failed or been skipped

A patch can be created by following Travis CI's docs on adding apt packages:
