Subject: [PATCH] conf: fix the export of safe_strto* functions from libasound

Only one library should define the safe_strto function. Export it
correctly and add _snd_ prefix to avoid possible clashes with the other
application code.

Fixes: 47252054 ("src/topology/parser.c: drop duplicate safe_strtol_base")
Fixes: https://github.com/alsa-project/alsa-lib/pull/208
