[test] Move to earlier deployment target as workaround

We are already using 5.4 target as a workaround for missing
LC_DYLD_CHAINED_FIXUPS support in reflection tools, but we need to
further workaround a linker bug in older versions of ld-prime that
caused appletv simulator platform to be misidentified and use chained
fixups earlier than it should, so move back to 5.2.
