ARROW-13803: [C++] Don't read past end of buffer in BitUtil::SetBitmap

I can only get this to actually fail on M1 ARM with optimizations, but what happens here is we read one past the end of a buffer. On M1, this actually ends up in an unmapped region, crashing the program.

On Linux/x64, I tried AddressSanitizer and Valgrind but neither caught the access, oddly enough.

Closes #11070 from lidavidm/arrow-13803
