perf tests: Add a test for the ARM 32-bit [vectors] page

perf on ARM requires CONFIG_KUSER_HELPERS to be turned on to allow some
independance with respect to the ARM CPU being used. Add a test which
tries to locate the [vectors] page, created when CONFIG_KUSER_HELPERS is
turned on to help asses the system's health.
