Fix MinGW64/MSYS2 w/GCC 15.1 warning 

As reported by Steve, VK3SIR on the mailing list:

On compilation, through a fully up-to-date MinGW64/MSYS2 environment, we receive the following warnings:

....

The '%z' modifier is also found in rigs/icom/icom.c but with a 'u'
conversion specifier.  Turns out that since 'needed' in this function is
of type 'size_t' which is an unsigned integer so the 'u' is required.
