Florian Weimer ef0700004b stdlib: Simplify buffer management in canonicalize ...

Move the buffer management from realpath_stk to __realpath.  This
allows returning directly after allocation errors.

Always make a copy of the result buffer using strdup even if it is
already heap-allocated.  (Heap-allocated buffers are somewhat rare.)
This avoids GCC warnings at certain optimization levels.
