tests/lib/ringbuffer failed on ARC boards

[IRISZZW]

Describe the bug tests/lib/ringbuffer failed on ARC boards: hsdk, qemu_arc_hs, nsim_hs_smp

To Reproduce Steps to reproduce the behavior:

1. west build -b hsdk -d build tests/lib/ringbuffer
2. west -v flash -r mdb-hw --cores=4
3. See error

[yerabolu]

fails on up_square, EHL_CRB and Microchip as well.

[enjiamai]

fails on ACRN ehl_crb as well.

[evgeniy-paltsev]

As I can see from verification it fails (sporadically) on qemu_x86 as well:

tests/lib/ringbuffer/libraries.data_structures     FAILED Timeout (qemu)
