cleanup: remove left files after test finishes
Fix file leak in _get_max_file_size - This is obviously mostly
problematic for FS lacking support for sparse files.
There seems to be some seek_sanity_testfile files that are not
cleaned up and take up space:
-rwxr-xr-x. 1 root root 8.0G Sep 22 13:39 seek_sanity_testfile10
g/394: Clean up test files taking space:
-rwxr-xr-x. 1 root root 1.0G Sep 22 14:58 394.1183899
-rwxr-xr-x. 1 root root 1.0G Sep 22 14:58 394.1183899-1
-rwxr-xr-x. 1 root root 0 sep 22 14:58 394.1183899+1
