Resolves: #i124896# [API CHANGE] remove obsoleted rtl/allocator.hxx

remove obsoleted sal-module-internal custom STL allocator

The SAL module avoided the heavy dependency on the stlport4-libraries by using
a custom allocator for its internal STL containers. With stlport4 removed these
dependencies are gone and the SAL-internal custom allocator is obsoleted.

(cherry picked from commit c6e0325df6efce45dbb2616a32b7745c449c6c58)
