Fix leak of identifier in macro definition.
Valgrind detects leaks like the following (gdb.base/macscp.exp).
This patch fixes 1 of the 3 leaks (the last one in the list below).
The remaining leaks are better fixed in splay_tree_remove and
splay_tree_insert in libiberty.
Tested on debian/amd64, natively and under valgrind.

* macrocmd.c (extract_identifier): Return
a gdb::unique_xmalloc_ptr<char> instead of a char *, and update
callers.
