ParseXS: refactor: chomp TYPEMAP lines

(This commit is part of a series which will extend the AST parse tree
from just representing individual XSUBs to representing the whole XS
file.)

For consistency with everything else in fetch_para(), chomp any lines
extracted from a TYPEMAP section before stuffing them in
@{$pxs->{line}}. Later, make Node::TYPEMAP::parse() stick a newline
back on each line before passing them to the typemap parser.
