lib/libgcc.c: Fix shift warnings

```
  if (!(a & (0xffff << 16))) {
                    ^~
src/lib/libgcc.c:40:18: error: result of '255 << 24' requires 33 bits to represent, but 'int' only has 32 bits [-Werror=shift-overflow=]
  if (!(a & (0xff << 24))) {
                  ^~
src/lib/libgcc.c:45:17: error: result of '15 << 28' requires 33 bits to represent, but 'int' only has 32 bits [-Werror=shift-overflow=]
  if (!(a & (0xf << 28))) {
                 ^~
```
