fix: tie compaction probe build to CONFIG_COMPACTION

The definition of 'struct compact_control' in 'mm/internal.h' depends on
CONFIG_COMPACTION being defined. Only build the compaction probe when
this configuration option is enabled.

Thanks to Bruce Ashfield <bruce.ashfield@gmail.com> for reporting this
issue.
