OPP: Add local support for file transfer error text.

Usecase:
1) Set Language on DUT to Turkish.
2) Transfer a file > 4GB and observe

Expectation:
Error message if any should be shown in system laguage set on DUT.

Observation:
Error message is displayed in English instead of Turkish

Fix:
Show file limit message through localized version of getString()
instead of as hardcoded item from code.

Test: Checked that error mesage is not displayed in english if DUT
system language is different from english.
