main/libexecinfo: change upstream
the existing libexecinfo doesn't actually work whatsoever, and basically call to backtrace() segfaults or returns 0 frames.
this slightly updated version from freebsd returns.. 1 frame with optimisations, or works correctly with -O0, which is a little better, at the price of libelf.
imo, either we should upgrade to this, or patch out libexecinfo in the 20 dependents and remove this library- the functionality itself is not very useful and scarcely used (and never for anything exceedingly useful, just printing a stack on crash), and the library doesn't work at all (currently) anyway.
