Avoid uninitialized variable btilde

Browse Source 
Pre-initialize this variable. It should be set in pucch2x_scrambling(),
but the compiler warns with

    In function ‘pucch2x_modulation’,
        inlined from ‘generate_pucch2x’ at oai/openair1/PHY/LTE_UE_TRANSPORT/pucch_ue.c:425:3:
    oai/openair1/PHY/LTE_UE_TRANSPORT/pucch_ue.c:361:18: warning: ‘btilde’ may be used uninitialized [-Wmaybe-uninitialized]
      361 |     d[i] = btilde[i] == 1 ? -amp : amp;
