[PATCH] ima-evm-utils: Namespace some too generic function names

[Vitaly Chikunov <vt@altlinux.org>]

Prefix `dump', `do_dump', and `params' with `ima_' to avoid colliding
with other global symbols.

`params' is prefixed with a #define trick to avoid change in half
hundred places.

Signed-off-by: Vitaly Chikunov <vt@altlinux.org>

I think all other exported functions (good example is verify_hash) should be
prefixed too.
