Add permissions in profcollectd to parse kernel etm data.

To parse etm data for kernel and kernel modules, add below permissions
to profcollectd:
1. Get kernel start address and module addresses from /proc/kallsyms
and /proc/modules.
2. Get kernel build id from /sys/kernel/notes.
3. Read kernel module files in vendor dir.

Bug: 166559473
Test: run profcollectd.
