Fix compatibility breakage with wxMask::Create() in wxOSX (#1019)

Browse Source 
Defining a Mac-specific Create(wxMemoryBuffer) overload hid the other
Create() overloads, which are actually part of the public API, so they
couldn't be used any longer since the changes of
e7d21f6638

Fix this by renaming this Create() to OSXCreate(), to avoid hiding the
base class methods.

Also remove Mac-specific ctor taking wxMemoryBuffer, this is confusing
and can be avoided by just calling OSXCreate() directly in the only
place where it is used.
