[PATCH v2] selftests: size: fix grammar and align output formatting

[Abdelrahman Fekry <abdelrahmanfekry375@gmail.com>]

This is v2 of the patch. 
The Signed-off-by line mismatch reported by checkpatch
has been fixed.

Improve the grammar in the test name by changing "get runtime memory use"
to "get runtime memory usage". Also adjust spacing in output lines
("Total:", "Free:", etc.) to ensure consistent alignment and readability.
