tests: arch: common: ramfunc: fix the project's name in CMake

The name used in CMakeLists for this test is "zero_latency_irqs" despite
testing the ramfunc feature instead. This might be a copy-paste mistake
as it was originally "arm_zero_latency_irqs", which is another test that
exists.

Change the project name in CMakeLists to match what the test truly is.
