Use external classes in @run driver

There's at least a couple of things going on here.

1. external.lib.roots is only used for library code that is outside the 
current test suite (i.e. outside the directory containing TEST.ROOT)
     It provides root directories in which to resolve @library 
directories that begin with '/'.
     In other words, if you have
         @library /my/lib
     and you have
         external.lib.roots=../A ../B
     Then jtreg will look for library files in TESTROOTDIR/my/lib, 
     where TESTROOTDIR is the root directory of the test suite.

2. There's something weird the output you posted:
TIME: .lib.FileInstaller seconds
     If that's what jtreg wrote, that is an unexpected error in jtreg

3. Minor: the current released version of jtreg is 5.1, as indicated by 
the Mercurial tag jtreg5.1-b01
     The default version of 5.2 in the tip changeset will be the version 
of the next update.
