generic/352: require no compression

generic/352: require no compression

Our CI has been failing on this test for compression since 0fc226e7
("fstests: generic/352 should accomodate other pwrite behaviors").  This
is because we changed the size of the initial write down to 4k, and we
write a repeatable pattern.  With compression on btrfs this results in
an inline extent, and when you reflink an inline extent this just turns
it into full on copies instead of a reflink.

As this isn't a bug with compression, it's just not well aligned with
how compression interacts with the allocation of space, simply exclude
this test from running when you have compression enabled.
