[behavior][XWALK-2495] Rename file name for behavior.

- Fix bug fail to install wgt when the file name includes specific character on IVI
Seems XWALK-2495 is a real implementation bug, and this pull request is just workaround!

Search `eAAC` and `eAAC+` via google.com, you will get totally different results! This is because `eAAC+` is a short name of **High-Efficiency Advanced Audio Coding (HE-AAC)**, see http://en.wikipedia.org/wiki/High-Efficiency_Advanced_Audio_Coding

So please rename `eAAC+` to `HE-AAC` for this workaround. Please also add comment to the bug showing this is just a workaround.
