kcov: add missing #include <linux/sched.h>
In __sanitizer_cov_trace_pc we use task_struct and fields within it, but as we haven't included <linux/sched.h>, it is not guaranteed to be defined. While we usually happen to acquire the definition through a transitive include, this is fragile (and hasn't been true in the past, causing issues with backports). Include <linux/sched.h> to avoid any fragility.
