Limit Derby external test to startup verification

Replace full junit-all test suite with startup-only verification using
Derby's built-in sysinfo tool. The sysinfo command exercises JVM launch,
Derby class loading, and runtime reflection without running Derby's own
application-level unit tests.

Also fix pre-existing bash syntax bug: 'export var value' (without =)
does not assign the variable in bash; corrected to 'export var=value'.

- external/derby/test.sh: remove ant junit-all; fix export syntax; run
  java -jar derbyrun.jar sysinfo as the startup signal
- external/derby/playlist.xml: add derby_startup_test at extended level;
  demote derby_test_junit_all to special level (on-demand only)
