perf config: Make symbol_conf::addr2line_disable_warn configurable

Make symbol_conf::addr2line_disable_warn configurable by reading
the perfconfig file.
Use section core and addr2line-disable-warn = value.
Update documentation.

Example:
 # perf config -l
 core.addr2line-timeout=5000
 core.addr2line-disable-warn=1
