tool/extlibs.rb: Use Exception#message for older rubies
This script runs with BASERUBY, which can be as old as 2.2.x. Exception#full_message is new in 2.5.0.
I saw a NoMethodError on the AppVeyor CI where BASERUBY is 2.4.6: https://ci.appveyor.com/project/ruby/ruby/builds/43870654/job/kae4uo2xbhuhqmdw#L121
