The libgcrypt library has several deprecated functions exported, that we don't use.
Unfortunately the GCC compiler warns about these deprecated functions regardless,
which is quite annoying. This commit makes clang/gcc ignore the deprecated attribute,
for gcrypt.h only. The danger with this is if gcrypt ever deprecates a function
we actually *use*, then we won't see the warning. So I'm not sure if it's a good or
bad idea to do this change, but it's really annoying to see the warnings and makes
finding real warnings difficult.
