xfstests: xfs_tosspages() test addition

Browse Source 
Tests the XFS_IOC_ZERO_RANGE ioctl by way of the "xfs_io zero" utility
to ensure it is tossing the expected ranges.

The ranges tested are [0,1] [0,4095] [0,4096] [0,4097] [4095,8191]
  [4095,8192] [4095,8193] [4096,8192] [1024,4096]

# FS QA Test No. 290
#
# Makes calls to XFS_IOC_ZERO_RANGE and checks tossed ranges
#
# Nothing should be tossed unless the range includes a page boundry
#
# Primarily tests page boundries and boundries that are
# off-by-one to ensure we're only tossing what's expected
