[libbacktrace] Simplify memory management in build_address_map
In the main loop in build_address_map, we first read the abbrevs into a local
variable abbrevs, and then allocate the corresponding unit, after which we assign
the abbrevs to the unit. This results in dedicated free-upon-failure
handling for the variable, and extra code to make sure that free-upon-failure
doesn't trigger once the unit has taken ownership of the abbrevs.
Simplify this by reversing the order of abbrev reading and unit allocation,
and eliminating the abbrevs local variable.
Bootstrapped and reg-tested on x86_64.
