BUILD: tools: fix minor build issue on isspace()

Previous commit fa41cb679 ("MINOR: tools: support for word expansion
of environment in parse_line") introduced two new isspace() on a char
and broke the build on systems using an array disguised in a macro
instead of a function (like cygwin). Just use the usual cast.
