Fix ASAN failure in bitrev_test

Previously while testing osmo_nibble_shift_left_unal() following error
was triggered by AddressSanitizer:

==3890== ERROR: AddressSanitizer: stack-buffer-overflow on address 0xbff5b5b6 at pc 0xb6186862 bp 0xbff5b4a8 sp 0xbff5b49c
READ of size 1 at 0xbff5b5b6 thread T0
    #0 0xb6186861 (/home/msuraev/source/gsm/libosmocore/src/.libs/libosmocore.so.7.0.0+0xc861)
    #1 0x8049d8b (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x8049d8b)
    #2 0x804a9d1 (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x804a9d1)
    #3 0xb5fe3af2 (/lib/i386-linux-gnu/libc-2.19.so+0x19af2)
    #4 0x8048a30 (/home/msuraev/source/gsm/libosmocore/tests/bits/.libs/lt-bitrev_test+0x8048a30)
Address 0xbff5b5b6 is located at offset 38 in frame <main> of T0's stack:
  This frame has 3 object(s):
    [32, 38) 'in2'
    [96, 104) 'out'
    [160, 168) 'in1'

The reason is incorrect range in test cycle. Fix it and adjust test
output accordingly.
