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. Change-Id: I2e0b346379271fadc20e720722f7c9a687335ee2
