LU-13268 tests: customize lnet-selftest for performance

Sometimes we need to run read/write/ping tests separately
with different lst check flags.

Patch allows to:
  set the required list of tests via new lst_TESTS variable;
  set lst check to LST_BRW_CHECK_NONE, LST_BRW_CHECK_FULL
      or LST_BRW_CHECK_SIMPLE.
