ima-evm-utils: Rework openssl init

Browse Source 
Remove deprecated call to OpenSSL_add_all_algorithms().
Allow to disable openssl config loading by evmctl via configure
`--disable-openssl-conf' option. Show status of that in configure.
Move config loading from libimaevm to evmctl.
Finish engine initialization properly by calling ENGINE_set_default(),
as suggested by James Bottomley.
