configure: Fix test for libunwind
Most functions in libunwind.h are actually mapped via macros to obscure
function names, so checking for these would require some elaborate test
via AC_LINK_IFELSE(). However, unw_backtrace() seems to be one of the few
actual functions so lets use this for now, even though we don't call it
ourselves later.
Fixes: 016228c15843 ("configure: Check for actual functions in libraries
with AC_CHECK_LIB")
