Enabling more coredumps

Though it may be possible to enable some Coredump features via setting registry values, patching for creating full Coredumps on CEX is required. There are 2 key patches. In the SceCoredump module, there are two functions that read values from the registry. The registry key used is "/CONFIG/COREDUMP".

The first patch is to force the function (located at base+0x3070 on 1.50) that checks the key "enable_coredump" to return 1 (True).

The second patch is to force the function (located at base+0x3000 on 1.50) that checks the key "dump_level" to return 0xEF0 (full coredump).
