fix(pkg-get): localize variable "file" properly

The variable `i` is declared but unused in
`_comp_cmd_pkg_get__catalog_file`.  The variable `file` is declared
but unused in `_comp_cmd_pkg_get`.  Instead, the variable `file` is
used inside `_comp_cmd_pkg_get__catalog_file`.  The variable `file`
should be declared inside `_comp_cmd_pkg_get__catalog_file` instead of
the variable `i`.
