tests: settings: fcb: increase ztest stack size to 2kB

Browse source 
Tests are passing now on `nrf52840dk_nrf52840` platform, just because ARM
MPU is disabled and stack overflow is not detected. When running those
tests on `qemu_x86` there is following error during runtime:

  START - test_config_compress_reset
  E: Double Fault
  E: EAX: 0x0011c1c8, EBX: 0x00000002, ECX: 0x00000002, EDX: 0x0000100a

  E: >>> ZEPHYR FATAL ERROR 2: Stack overflow on CPU 0
  E: Current thread: 0x11b140 (test_config_compress_reset)

Same happens on `nrf52840dk_nrf52840` when ARM MPU is enabled:

  START - test_config_compress_reset
  E: ***** MPU FAULT *****
  E:   Stacking error (context area might be not valid)

Increase ZTEST stack size to 2kB to prevent stack overflow.
