sdevent: Remove test from being built/run

The sdevent utility was replaced with use of sdeventplus and is no
longer used within any of the fan applications. Only the test code of
sdevent has continued to be built/run so its time to remove it.

sdevent was replaced by sdeventplus over a year ago by commit
1cfc2f11b13412a15f8478cebc35e50e6feb13a2

Tested:
    sdevent tests no longer run
