[B.A.T.M.A.N.] [PATCHv2 1/2] alfred-gpsd: Calculate size of global buffer and not of a single char

[Sven Eckelmann]

The global buffer is 65536 bytes in size and not only 1 byte. This statement
evaluated to a negative value which was casted to an unsigned value (aka...
very large value).

This is a regression was introduced in 71dbc00fd879f1e592b07d8397f724fb3f69ac64
("alfred: Use strncpy instead of strcpy for string").
