[Views] Fix Animated App Menu Icon Color on Linux

On Linux, the system theme is different from the
default theme, which causes the icon color to be
incorrectly set.

Tested this issue on Ubuntu 14.04 with chrome Beta #61.0.3163.59 & Canary #62.0.3198.0

Installed Test theme on both versions and observed the same behavior of 3 dot wrench icon color in both channels.

Attaching the screen-shot for reference.

spqchan@ Could you please look into it and let us know your observations.

Can you test this with --simulate-crtical-update? Both icons should be red

Tested the issue on Ubutu 14.04 using Chrome version M62 - 62.0.3198.0 as per the issue mentioned in original comment. Observed that issue is working as intended (3 dot menu button replaced with Update button and is displayed in red colour when chrome is launched with --simulate-critical-update). Hence adding TE-Verified label. Attached the screenshot for reference.

Thank you!
