jit: update test suite for change to -Warray-bounds

jit.dg/test-error-array-bounds.c is a test of how libgccjit
handles errors coming from the middle-end, using -Warray-bounds as
an example.

It started failing as of r254830 (aka 987b3316c4e7c908e3c7d2151c20971f9707ad66),
due to that commit changing the wording of the message.

This commit fixes the jit testcase by updating it to use the new
wording.
