evmctl defines the "--pass | -p" command line option for providing
the private key's password. The password is then stored in a global
variable accessible by the sign_hash_XXXX() functions.
This patch modifies the arguments to the library sign_hash()
function to include the password, allowing callers to specify the
private key password.

This patch enables package managers, such as rpm, to include IMA signatures in
packages.
To do this, sign_hash and some helper functions were moved from evmctl to
libimaevm. These functions used global variables that belong to evmctl, sigdump
and keypass. The variable sigdump is a flag that file signatures should be
printed to stdout, so the signature dump is now handled by functions that call
sign_hash. The variable keypass is a passphrase for an encrypted key, so it was
added to 'struct libevm_params'.
v2: Uses 'struct libevm_params' to minimize sign_hash parameters
v3: Export single sign_hash function that selects _v1 or _v2 internally based
on params.x509. Moved parameter checks and explicitly return -1 for failures.
