tests: add coverage to for `HGCB_BUNDLE_BASENAME` with special characters

Per request on IRC, to show the behavior of dropping the quoting of
`HGCB_BUNDLE_BASENAME` in the next commit.  This current failure is basically
the same error and output that currently happens on Windows with any path (even
without the embedded quote).  The only difference is Windows doesn't print the
`cp: cannot stat ...` line.
