[PATCH] kernel/crash: Remove inclusion of crypto/sha1.h

[Eric Biggers <ebiggers@kernel.org>]

Several files related to kernel crash dumps include crypto/sha1.h but
never use any of its functionality.  Remove these includes so that these
files don't unnecessarily come up in searches for which kernel code is
still using the obsolete SHA-1 algorithm.
