common/punch: Filter fiemap output by FS block size

Browse Source 
When testing FS instances of block size other than 4k, the output of
fiemap command will not match those in *.out files. This commit adds
an optional "block size" argument to _filter_fiemap() which prints
fiemap output in units of block size.
