s390/dis: use correct escape sequence for '%' character 

The double escape character sequence introduced with commit
272fa59ccb ("s390/dis: Fix handling of format specifiers") is not
necessary anymore since commit 561e103002 ("s390/dis: Fix printing
of the register numbers").

Instead this now generates an extra '%' character:

lg      %%r1,160(%%r11)

So fix this and basically revert 272fa59ccb.
