[PATCH 1/4] t7401: modernize style

[Shourya Shukla <shouryashukla.oo@gmail.com>]

The tests in 't7401-submodule-summary.sh' were written a long time ago
and have some violations with respect to our CodingGuidelines such as
incorrect spacing in usages of the redirection operator and absence
of line feed between statements in case of the '|' (pipe) operator.
Update it to match the CodingGuidelines.
