Ismael Luceno c1be123960 Add configure test for the backtrace implementation
Improve robustness by testing explicitly; instead of assuming based on
the OS, test first the libc and then test for libexecinfo.

The assumption was wrong for FreeBSD (included since 2017) and for
musl-based systems (not in libc).

Also, remove INCLUDE_BACKTRACE and clean up a bit.
