Fix: efm_perl missed some error messages

First example:

    $ echo -e 'if (0)\nsome();\n}' | perl -c -
    Semicolon seems to be missing at - line 1.
    syntax error at - line 2, near ")
    some"
    Unmatched right curly bracket at - line 3, at end of line
    - had compilation errors.

    $ echo -e 'if (0)\nsome();\n}' | perl syntax_checkers/efm_perl.pl -c -
    -:1:Semicolon seems to be missing

Second example:

    $ echo -e 'if (0)' | perl -c -
    syntax error at - line 1, at EOF
    - had compilation errors.

    $ echo -e 'if (0)' | perl syntax_checkers/efm_perl.pl -c -
