Hi all,


could you please review the clean-up of nsk_jdb tests? 
from main issue(8204985) :
> all vmTestbase tests have '@run driver jdk.test.lib.FileInstaller . .' to mimic old test harness behavior and copy all files from a test source directory to a current work directory. some tests depend on this step, so we need 1st identify such tests and then either rewrite them not to have this dependency or leave FileInstaller only in these tests.


the patch removes FileInstaller actions in all the tests. as in all previous patches, the biggest (and tedious) part of the patch is just `ag -l  '@run driver jdk.test.lib.FileInstaller . .' $DIR  | xargs -I{} gsed -i '/@run driver jdk.test.lib.FileInstaller \. \./d' {}` with $DIR being test/hotspot/jtreg/vmTestbase/nsk/jdb/; two tests however required manual intervention: nsk/jdb/read/read001 and use001/use001 were misusing `-workdir` option. these tests expected this option to point to the directory w/ test's source code. 'workdir' option is processed by nsk/share/jdb/JdbArgumentHandler and is meant to store "full path to current test directory", which obviously doesn't have to be in the source tree. the tests were updated to use `test.src` property value instead of `workdir`.

testing: :vmTestbase_nsk_jdb on linux-x64
JBS: https://bugs.openjdk.java.net/browse/JDK-8249040

Thanks,
