fs/squashfs: needs more test cases

Browse Source 
For the new patch, adding block size options (commit 555f8dfd),
Yann E. MORIN requested updated testcases that specifically ensure
the extreme blocksizes (4K and 1024K) don't cause issues.

This patch splits the current test case in 2, testing with both
block sizes and ensuring the block size was applied in the same
fashion as for the specified compression.
