[PATCH RESEND] examples/vm_power_manager: add missing <stdlib.h> header include for strtol

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

From: Guillaume Gardet <Guillaume.Gardet@arm.com>

strtol is defined in stdlib.h

Fixes the following build failure:

../examples/vm_power_manager/guest_cli/vm_power_cli_guest.c: In function ‘cmd_query_freq_list_parsed’:
../examples/vm_power_manager/guest_cli/vm_power_cli_guest.c:208:42: error: implicit declaration of function ‘strtol’; did you mean ‘strtok’? [-Wimplicit-function-declaration]
  208 |                 lcore_id = (unsigned int)strtol(res->cpu_num, &ep, 10);
      |                                          ^~~~~~
      |                                          strtok

Fixes: 0e8f47491f090f44a4956429cb27f6942b6618b0 ("examples/vm_power: add command to query CPU frequency")
