When UBSan was enabled and 'make test' was executed, the following
runtime error was observed:
libradamsa.c:26055:29: runtime error: left shift of 16777215 by 8 places cannot be represented in type 'int'
This issue was caused by a left shift operation on a signed integer.
The fix involved changing the integer literal to an unsigned integer by
adding a 'U' suffix, ensuring the left shift operation produces the
correct value without overflow.
Fixes: 8178f4df ("remove radamsa, add radamsa custom mutator")

This variable is a standard way to inject options for the C
preprocessor. It's respected by the implicit rules of make
and autoconf/automake.
Debian sets this variable during package build to inject
`-D_FORTIFY_SOURCE=2` and we would like afl++ to respect it.
Note that this commit also adds $(CFLAGS) in the build of
afl-performance.o where it was missing. It might have been
on purpose but we want to keep CFLAGS everywhere as well
since Debian injects various options through that variable
(for hardening and reproducibility).
