selftests/bpf: Drop subtest descriptions in jit_insns_arena

Browse Source 
Drop the redundant __description macros from arena_zero_off and
cast_to_user inside jit_insns_arena. This allows the test_loader
framework to automatically fallback to the snake_case C function
names rather than the description string for test display.

Before:

  $ sudo ./test_progs -t jit_insns/arena_zero_off | tail -3
  #191/1   jit_insns/arena access with zero offset:FAIL
  #191     jit_insns:FAIL
  Summary: 1/0 PASSED, 0 SKIPPED, 1/1 FAILED

  $ sudo ./test_progs -t jit_insns/cast_to_user
  #191/2   jit_insns/cast to a user address:OK
  #191     jit_insns:OK
  #192     jit_insns_blinded:OK
  Summary: 2/1 PASSED, 0 SKIPPED, 0/0 FAILED

After:

  $ sudo ./test_progs -t jit_insns/arena_zero_off | tail -3
  #191/1   jit_insns/arena_zero_off:FAIL
  #191     jit_insns:FAIL
  Summary: 1/0 PASSED, 0 SKIPPED, 1/1 FAILED

  $ sudo ./test_progs -t jit_insns/cast_to_user
  #191/2   jit_insns/cast_to_user:OK
  #191     jit_insns:OK
  #192     jit_insns_blinded:OK
  Summary: 2/1 PASSED, 0 SKIPPED, 0/0 FAILED

The main goal is that if a test fails, developers can immediately
recognize the exact, actionable test name from the standard output
and rerun it without any confusion.
