mit-krb5: Workaround for MSAN not handling getrandom
MSAN does not track memory writes by getrandom. Thus, anything that uses
the random numbers causes Use-of-uninitialized-value errors. This is a
false positive. As a workaround, set buffer to 0 before calling
getrandom.
I've verified that the random bytes are indeed written, just in case.
