[LTP] [PATCH v1] Fix memcontrol tests under Tumbleweed

[Marius Kittler]

These tests use `all_filesystems` in combination with
`dev_min_size` which does not work on Tumbleweed as it results
in:

```
tst_test.c:1644: TINFO: === Testing on xfs ===
tst_test.c:1099: TINFO: Formatting /dev/loop0 with xfs opts='' extra opts=''
Filesystem must be larger than 300MB.
…
tst_test.c:1105: TBROK: mkfs.xfs failed with exit code 1
```

This is likely a limitation introduced in newer kernel versions.

Increasing `dev_min_size` to 300 fixes the tests. In
`memcontrol03` and `memcontrol04` the `dev_min_size` setting
can be dropped completely.
