posix_cpu_timer: Convert cputimer->running to bool

Browse source 
In the next patch in this series, a new field 'checking_timer' will
be added to 'struct thread_group_cputimer'. Both this and the
existing 'running' integer field are just used as boolean values. To
save space in the structure, we can make both of these fields booleans.

This is a preparatory patch to convert the existing running integer
field to a boolean.
