nios2: ksyms: Declare __mulsi3 export

Browse Source 
GCC may emit libcalls to __mulsi3(). As modpost is not aware that this
function is provided through the linked in libgcc, it fails:

ERROR: modpost: kernel/locking/test-ww_mutex.ko: symbol '__mulsi3' undefined!
ERROR: modpost: kernel/time/test_udelay.ko: symbol '__mulsi3' undefined!
ERROR: modpost: kernel/resource_kunit.ko: symbol '__mulsi3' undefined!
ERROR: modpost: fs/fuse/virtiofs.ko: symbol '__mulsi3' undefined!
etc.

Make sure modpost can see the symbol from libgcc.
