cpusensor: Search in peci-0 directory
The code was searching /sys/bus/peci/devices for PECI sensors.
This results in below directories to be searched on typical 2 socket
x86 systems.
* peci-0
* 0-30
* 0-31
Where 0-30 and 0-31 exist in peci-0 as well.
It is unnecessary, and the files in 0-30 and 0-31 will be searched twice
because they exist in peci-0.
Change the code to search in /sys/bus/peci/devices/peci-0 to make sure
it only search the files within the expected directory.
Note that the current peci driver only create peci-0, this code could be
easily extended to support peci-1/2/3 in the future.
Tested: The time for cpusensor to search the peci sensors reduces from
0.5s to about 0.3s.

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
