Set path_info in sub_slo manifest GET requests

The new_req Request object created for fetching
nested sub_slo manifests does not have its
path_info set to the sub_slo path before being
passed to GETorHEAD_base.

The sub manifest GET works fine because
GETorHEAD_base uses its path argument
(not req.path) to set up its connection,
BUT if an exception is thrown,
GETorHEAD_base uses req.path to construct
the log message - so the exception log would
have the wrong path.

Fixes bug 1231872
