[lldb][NFC] update API tests which skip/expect-fail arm

The architectures provided to skipIf / expectedFail are regular
expressions (v. _match_decorator_property() in decorators.py
so on Darwin systems "arm64" would match the skips for "arm" (32-bit
Linux).  Update these to "arm$" to prevent this, and also update
three tests (TestBuiltinFormats.py, TestCrossDSOTailCalls.py,
TestCrossObjectTailCalls.py) that were skipped for arm64 via this
behavior, and need to be skipped or they will fail.

This was moviated by the new TestDynamicValue.py test which has
an expected-fail for arm, but the test was passing on arm64 Darwin
resulting in failure for the CIs.
