Fix deps link of perfmark

Issue: The perfmark link point to nothing since the path is
io_perfmark_perfmark_api. Anyone try to use this dep in the BUILD file,
they will face an error as following:
"no such target '@io_grpc_grpc_java//core:perfmark': target 'perfmark'
not declared in package 'core' defined by /private/var/tmp/xxxx/6f6008
fff2843565525304b248809a4a/external/io_grpc_grpc_java/core/BUILD.bazel
and referenced by '//deps:io_grpc_grpc_core_perfmark'"

The real path for perfmark is:
/private/var/tmp/xxxx/6f6008fff2843565525304b248809a4a/external/
io_perfmark_perfmark_api/jar/

Patch: Since the dep is no longer inuse in onos, removed this dep from deps/BUILD.
