Since we are increasing this we should probably check the free space as
well, so we should add something as:

	if (!tst_fs_has_free(".", appends, writesize))
		tst_brk(TCONF, "Not enough space to run the test");

Or even better put a function:

void tst_assert_free_space(const char *path, unsigned int size, unsigned int mult)

into the test library and this function would tst_brk(TCONF, ) if there
is not enough space and tst_res(TWARN, ) if the free space is let's say
only 10% more than the test would need to run. And we can use that in
all of these tests.
