xdiff/xmacros.h: remove unused XDL_PTRFREE 

This macro was added in 3443546f6e (Use a *real* built-in diff
generator, 2006-03-24), but none of the xdiff code uses it, it uses
xdl_free() directly.

If we need its functionality again we'll use the FREE_AND_NULL() macro
added in 481df65f4f (git-compat-util: add a FREE_AND_NULL() wrapper
around free(ptr); ptr = NULL, 2017-06-15).
