fs: fix binary file truncation in inmemory_fopen

When opening a file for reading, use the stored file size instead of
strlen. Since binary files can contain null bytes, strlen would
incorrectly truncate the file content, causing read operations to return
incomplete data.

This is purely test code, but should still fix it.
