build: make libunwind linked dynamically (#36697)

Not sure why this was first linked statically, as the commit that
introduced this simply had the message "restoring stuff that seems to
have been clobbered by the revert of the unintended merge to master".

Nearly all other libraries that we use are linked dynamically.
