Subject: [PATCH] GCC: fix template specialization in webrtc::BitstreamReader

GCC complains that explicit specialization in non-namespace scope
is happening for webrtc::BitstreamReader::Read(). However, specialization
for bool isn't used because std::is_unsigned<bool>::value returns true.
Add std::is_same for bool check and enable second specialization only
for bool types.
