Hi all,

could you please review the patch which removes `FileInstaller . .` jtreg action from :vmTestbase_vm_metaspace tests?
from the 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.

as none of these tests need FileInstaller, the patch is as simple as `ag -l  '@run driver jdk.test.lib.FileInstaller . .' vmTestbase/metaspace/ xargs -I{} gsed -i '/@run driver jdk.test.lib.FileInstaller \. \./d' {}`.

testing: :vmTestbase_vm_metaspace on linux-x64
webrev: http://cr.openjdk.java.net/~iignatyev//8249033/webrev.00
JBS: https://bugs.openjdk.java.net/browse/JDK-8249033

Thanks,
