largefiles: use the core file copy logic to validate the destination path

The destination is validated by pathutil.canonpath() for illegal components, and
that it is in the repository.  The logic for creating the standin directory tree
was calling this before cmdutil.copy(), but without the destination file name
component.  The cmdutil.copy() logic also calls pathutil.canonpath(), but with
the file name component.  By always calling the core logic first, the error
message is always consistent.  Specifically, the old behavior for these tests
was to say '.hg' contains an illegal component, and '..' is not under root.

A user wasn't likely to notice the discrepancy, but this eliminates a needless
difference when running the test suite with --config extensions.largefiles=.
