Don't say "syntax error" twice.

1) yyerror() isn't necessarily called on a syntax error, so rename the
routine it calls from bpf_syntax_error() to bpf_parser_error(), and
don't have that routine say "syntax error in filter expression", just
have it say "can't parse filter expression".

2) If it *is* called on a syntax error, the error message will probably
be "syntax error", so you end up saying "syntax error in filter
expression: syntax error", which is redundant, so just have it say
"can't parse filter expression".
