[PATCH 3/3] perf addr2line: Remove global variable addr2line_timeout_ms

[Thomas Richter <tmricht@linux.ibm.com>]

Remove global variable addr2line_timeout_ms and add is as member
to symbol_conf structure. No functional change.

Fixes: 257046a36750a ("perf srcline: Fallback between addr2line implementations")
