[testsuite] scandump.exp: use printable version of regexp

Most scan-* procedures used in dg-final test directives use a printable
version of the regular expression in the test summary.  This patch makes
scan-*-dump-tiles do that as well, which eliminates several duplicates
in test summaries for expressions that contain a newline.

Tested on i686-pc-linux-gnu and arm-none-eabi.  OK for mainline?

Ok.
