zram01.sh: Fix minimal size for XFS on kernel 5.19

mkfs.xfs for kernel 5.19 bumps minimum filesystems 300 MB. Due this we
already updated minimal filesystem size for all_filesystems /
$TST_ALL_FILESYSTEMS in 66e05c8. But zram01.sh does not use the API,
thus update it now.

Also require 1G of RAM for XFS (check originally added in f18c8fd for
Btrfs on ppc64le due to larger page size, likely needed for also XFS).
