[NFC][BoundsSafety] Fix UBSan test cases added for swiftlang#11645

In swiftlang#11645 test cases combining `-fbounds-safety` trap mode with UBSan in
trapping mode. The generated IR includes a global string array that
contains  an absolute file path. The test case was previously manually
patched so that any path would match to make the test case portable.

However, the length of the constant array was not changed which still
meant the test wasn't portable. This fixes that by allowing any length
for the global arrays
