    wifi-scripts: fix RX-STBC notation VHT capabilities
    
    Notation for RX-STBC VHT capabilities when specifying number of spatial
    streams should be hyphenated, e.g. RX-STBC-1, RX-STBC-2. HT capabilities
    use without hyphen, e.g. RX-STBC1, RX-STBC2. This is consistent with
    what hostapd expects.
    
    ```c
    static int hostapd_config_ht_capab(struct hostapd_config *conf,
                                       const char *capab)
    {
            if (os_strstr(capab, "[RX-STBC1]")) {
                    conf->ht_capab &= ~HT_CAP_INFO_RX_STBC_MASK;
                    conf->ht_capab |= HT_CAP_INFO_RX_STBC_1;
            }
            if (os_strstr(capab, "[RX-STBC12]")) {
                    conf->ht_capab &= ~HT_CAP_INFO_RX_STBC_MASK;
                    conf->ht_capab |= HT_CAP_INFO_RX_STBC_12;
            }
            if (os_strstr(capab, "[RX-STBC123]")) {
                    conf->ht_capab &= ~HT_CAP_INFO_RX_STBC_MASK;
                    conf->ht_capab |= HT_CAP_INFO_RX_STBC_123;
            }
    }
    
    static int hostapd_config_vht_capab(struct hostapd_config *conf,
                                        const char *capab)
    {
            if (os_strstr(capab, "[RX-STBC-1]"))
                    conf->vht_capab |= VHT_CAP_RXSTBC_1;
            if (os_strstr(capab, "[RX-STBC-12]"))
                    conf->vht_capab |= VHT_CAP_RXSTBC_2;
            if (os_strstr(capab, "[RX-STBC-123]"))
                    conf->vht_capab |= VHT_CAP_RXSTBC_3;
            if (os_strstr(capab, "[RX-STBC-1234]"))
    }
    ```
