[xad] lsar exceeds column width

[ci-macpaw]

Example:

228. -----          63  -713%  ----  2015-02-21 18:45  kmod-24/testsuite/rootfs-pristine/test-modinfo/correct-signer.txt
229. -----           3 -16967%  ----  2015-02-21 17:39  kmod-24/testsuite/rootfs-pristine/test-modinfo/correct-depends.txt

If there isn't enough space to print data into a column (like ratio here), print a replacement like <9999% or *****, but don't shift the following columns.

Moreover, three digits for the index seem insufficient and will shift columns after 1000 files.
