[PATCH] gitweb: Fix bug in insert_file() subroutine

[Jakub Narebski <jnareb@gmail.com>]

In insert_file() subroutine (which is used to insert HTML fragments as
custom header, footer, hometext (for projects list view), and per
project README.html (for summary view)) we used:

     map(to_utf8, <$fd>);

This doesn't work, and other form has to be used:

     map { to_utf8($_) } <$fd>;

Now with test for t9600 added, for $GIT_DIR/README.html.

I'm extremely sorry about that, but it still had bugs. I thought
I could use "map EXPR,LIST" form instead of "map BLOCK LIST" here,
i.e. "map(to_utf8, <$fd>)" instead of "map {to_utf8($_)} <$fd>;"
in original patch by Tatsuki Sugiura.

Just in case I have added check for this in t9500 gitweb test.

Once again, I'm very sorry for my buggy patches...
