lttng-modules: fix build against mips and v5.19 kernel

When building against a v5.19 mips kernel, the following errors
were triggered:

The root cause appears to be that this particular mips kernel does not
have CONFIG_COMPACTION avaiable, and hence we end up with the struct
declaration within this tracepoint, and then conflicting types.

While putting the conditional around only compaction_migratepages seemed
sufficient to get the build working, it doesn't look like any of the
tracepoints should be valid, so we extend it to all definitions.
