Fix jit test case (PR jit/88747)

Amongst other changes, r266077 updated value_range_base::dump so
that it additionally prints the type.  This broke an assertion within
the jit testsuite, in jit.dg/test-sum-of-squares.c, which was checking
for:
  ": [-INF, n_"
but was now getting:
  ": signed int [-INF, n_"

The test is merely intended as a simple verification that we can read
dump files via gcc_jit_context_enable_dump.

This patch loosens the requirements on the dump so that it should work
with either version of value_range_base::dump.

gcc/testsuite/ChangeLog:
	PR jit/88747
	* jit.dg/test-sum-of-squares.c (verify_code): Update expected vrp
	dump to reflect r266077.
