fa8dad0e078c577d740a9667636733957586c035 rpc: Fix implicit-integer-sign-change in verifychain (MarcoFalke)

Pull request description:

  It doesn't really make sense to treat `DEFAULT_CHECKLEVEL` as unsigned as long as `VerifyDB` accepts a signed integer.

  Making it signed also avoids a cast round trip from signed->unsigned->signed in the RPC.
