pseudotalloc: Add simplistic implementation of talloc_asprintf
fsm.c uses this function. When compiled with --enable-embedded, it
triggers a warning:
fsm.c: In function 'osmo_fsm_inst_alloc':
fsm.c:213:4: warning: implicit declaration of function 'talloc_asprintf' [-Wimplicit-function-declaration]
fi->name = talloc_asprintf(fi, "%s(%s)", fsm->name, id);
