check_seapp: correct output on invalid policy file

If in invalid policy file is loaded check_seapp outputs:

Error: Could not lod policy file to db: Success!

The "Success" value is from errno, which is not manipulated
by libsepol. Also, load should have an a in it!

Hardcode the error message to:

Error: Could not load policy file to db: invalid input file!

Test: That when providing an invalid sepolicy binary, that the output
message is correct.
