libext2fs: fix printf conversion spec in tst_iscan.c

A recent patch to fix blk_t to blk64_t assignment mismatches in
e2fsprogs (commit 4dbfd79d1458ce1259b951377e341aeb6197f8c1) created
a printf conversion spec / argument type mismatch in tst_iscan.c.
Fix this to avoid truncation of the printed value and to silence
a compiler warning seen when "make check" is run.
