Use EXPECT_EQ directly instead of EXPECT_STREQ in blink

As the first step to deprecate WTF::CString, the bug has suggested replacing
EXPECT_STREQ with EXPECT_EQ. Although previous CLs have been replacing EXPECT_STREQ,
there are still remaining things. So, this CL cleans up the remaining things
as much as possible.
