simpleperf: record complete process name.
The kernel limits length of process name to 15. But many app processes
have name with length longer than 15. This patch records complete
process name: When receiving a comm record for a process, try reading
complete name from /proc/pid/cmdline and storing the name in the comm
record.
Bug: none
Test: run simpleperf manually, it shows complete app name in reports.
Test: run simpleperf_unit_test.
