CTestCustom: Suppress scanbuild warning on unsigned left shift
The Clang scanbuild tool warns:
Utilities/cmliblzma/liblzma/simple/x86.c:106:23: warning:
The result of the '<<' expression is undefined
src = dest ^ ((1u << (32 - i * 8)) - 1);
~~~^~~~~~~~~~~~~~~
AFAIK overflow of a left shift on an unsigned type is well-defined.
