[ipaccess-config] fix bugs in generating the PHYSICAL CONFIG attribute
... while asking the BTS to perform tests for us. The length of the ARFCN whitelist is the actual length in bytes, not the number of 16bit ARFCN numbers. Also, implement a limit, either by rxlevel or by number of ARFCN that should end up in the whitelist.
