[PATCH 1/8] Fix test whether kernel supports quotas

For all 2.6 kernels presence of quota support in kernel can be detected by
checking /proc/sys/fs/quota. This is actually more reliable than trying to
mount a filesystem with quota options (for example because SCRATCH_DEV does
not have to contain a filesystem type we are going to test).
