dsp/lossless.c: quiet int sanitizer warnings

Browse Source 
in calls to Clip255(); given the current implementation's use of a
logical shift the parameter is left as uint32_t and explicit casts are
added

clears warnings of the form:
src/dsp/lossless.c:52:18: runtime error: implicit conversion
from type 'int' of value -2 (32-bit, signed) to type 'uint32_t' (aka
'unsigned int') changed the value to 4294967294 (32-bit, unsigned)
