Now that the SHA-1 code is no longer used, remove it.

perf util: add a basic SHA-1 implementation2025-06-26T17:51:40+00:00Eric Biggersebiggers@kernel.org2025-06-25T20:23:09+00:00urn:sha1:43830468b6436811ff732b062f8d6306c6eddb77
SHA-1 can be written in fewer than 100 lines of code. Just add a basic
SHA-1 implementation so that there's no need to use an external library
or try to pull in the kernel's SHA-1 implementation. The kernel's SHA-1
implementation is not really intended to be pulled into userspace
programs in the way that it was proposed to do so for perf
(https://lore.kernel.org/r/20250521225307.743726-3-yuzhuo@google.com/),
and it's also likely to undergo some refactoring in the future. There's
no need to tie userspace tools to it.
Include a test for sha1() in the util test suite.
