gitweb: Fix mod_perl support.
ModPerl::Registry precompiles scripts by wrapping them
in a subroutine. This causes ordinary subroutines of the
script to become nested, and warnings appear:
gitweb.cgi: Variable "$path_info" will not stay shared
This warning means that $path_info was declared as 'my',
and thus according to the perl evaluation rules all nested
subroutines will retain a reference to the instance of the
variable used in the first invocation of the master script.
When the script (i.e. the master meta-subroutine) is executed
the second time, it will use a new instance, so the logic
breaks. To avoid this it is necessary to declare all global
variables as 'our', which places them at the package level.
