libbacktrace: support fetching executable name using sysctl
This supports FreeBSD and NetBSD when /proc is not mounted.
libbacktrace/
* fileline.c (sysctl_exec_name): New static function.
(sysctl_exec_name1): New macro or static function.
(sysctl_exec_name2): Likewise.
(fileline_initialize): Try sysctl_exec_name[12].
* configure.ac: Check for sysctl args to fetch executable name.
* configure: Regenerate.
* config.h.in: Regenerate.
