* log.h: Change prototype for zlog_backtrace_sigsafe to take additional
program_counter argument.
* log.c: (zlog_backtrace_sigsafe) Add additional program_counter
argument. If it is non-NULL, use backtrace_symbols_fd to resolve
the address.
(zlog_signal) Call zlog_backtrace_sigsafe with additional
program_counter argument.
