editors/vscode: remove USE_LDCONFIG and add BUNDLE_LIBS

Shared libraries installed along with vscode are for internal use and
not intended for public consumption.

Remove USE_LDCONFIG so as not to add the shared library directory to
search paths. Add BUNDLE_LIBS so that pkg(8) does not pick the shared
libraries up for packaging.

Bump port revision for package change.
