[PATCH 7] gitweb: Cleanup - chomp @lines in consistent style

[Jakub Narebski <jnareb@gmail.com>]

Use 'my @lines = map { chomp; $_ } <$fd>;' form to read all lines of
git command output into array without trailing newlines.

It has advantage over 'chomp (my (@lines) = <$fd>);' in that it does
not modify array.
