[PATCH 12/27] fs-tests: integck: move more variables to fsinfo

[Artem Bityutskiy <dedekind1@gmail.com>]

From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Aggregate all the information about the tested file-system in
the fsinf object for better readability and cleanness. Move
'can_mmap' and 'check_nospc_files' there as well.
