parser: bugfix: set line number on <lineno> tokens.

This issue was revealed as a garbage line number in
an unbound variable warning diagnostic, where the variable
occurs in a quasi word list literal. A small test case
is (list #`@var`) where var unbound.

The fix is, in the lexer, to set the yylval->lineno for all
tokens which are declared as <lineno> in the grammar file,
for which doing so has beens neglected.  We do this even for
those tokens whose line number values are never accessd in any
rule; it could arise in the future.

* parser.l (grammar): Set the yylval->lineno for the tokens
HASH_BACKSLASH, HASH_B_QUOTE, HASH_SLASH, WORDS, WSPLICE,
QWORDS and QWSPLICE.
