Subject: remove one un-needed static initializer

remove one un-needed static initializer

This patch removes the use of a static C++ object in the
implementation of SkMatrix44::isIdentity(). Instead, we rely
on direct comparison with a statically allocated array of
SkMScalar values, which is completely equivalent.
