Resolve paths before checking app identity

Commands entered with a path do not match is_app. I encountered this
when working with a test for the rm_dir rule. This rule did not use the
@for_app decorator, but when I migrated it, the test for "./bin/hdfs.."
failed because 'hdfs' was recognized as a command, while "./bin/hdfs"
was not.

This commit addresses the false negative by resolving path names in the
command, via os.path.basename.
