[PATCH v3 1/3] chrt: Make minor cleanups in chrt

Minor changes such as fixing an incorrect comment and aligning
the closing brace of an if condition in main() were made, along
with making the usage of --pid consistent across files instead
of -p, although -p still works, for better readability.

No functional change is intended.
