webos-image: gtest=r2

:Release Notes:
Provide explicit bool conversion for ASSERT_TRUE and EXPECT_TRUE
macroses in gtest

:Detailed Notes:
In the expansion of ASSERT_TRUE and EXPECT_TRUE macros AssertionResult
is constructed from passed argument. When the type of the argument
declares an explicit operator bool() and an explicit conversion is
required, the compilation fails

:Testing Performed:
Build tested
MiniBAT

:QA Notes:
No functional changes to the image

:Issues Addressed:
[BHV-5239] gtest: Use explicit bool conversion in EXPECT_TRUE and
           ASSERT_TRUE macros
[BHV-9403] CCC: gtest=r2
