[PATCH] maint: style fixes in configure.ac

No semantic change is intended nor expected.  In fact, the 'configure'
files generated before and after this change are *exactly* the same.

* testsuite/runtest: Better use of m4 quotation throughout the
file.
(AC_CONFIG_FILES): No need to use trailing '\' when breaking
over multiple lines.
