  maplexer.l: avoid warning about isatty() on Windows

The latest regeneration of maplexer.c with a more recent version of flex
caused isatty() to be called, which caused a warning when building on Windows.
Parsing from an interactive terminal is not a use case for mapserver, so
add `%option never-interactive`.
