Kernel: Check kernel symbol's name length matches searched name

Browse source 
The current implementation would only check the first name.length()
characters match, which means any kernel symbol that the provided name
is a prefix of would match, instead of the actual matching symbol.

This commit fixes that by using StringView::operator==() for the
comparison, which already checks the equality correctly.
