[PATCH] gitweb-lib.sh: Set up PATH to use perl from /usr/bin

["Torsten Bögershausen" <tboegi@web.de>]

When there are different version of perl installed on the machine,
the $PATH may point out a different version of perl than /usr/bin.
One example is to have /opt/local/bin/perl before /usr/bin/perl.

Sanitize the PATH by adding /usr/bin at the beginning

On my Mac OS machine t9501-gitweb-standalone-http-status.sh failed because
perl was found under /opt/local/bin instead of of /usr/bin.

/opt/local/bin is coming from Macports.
The problem with different perl installations on the same machine
may hit more people than just me.

There are different solutions, please help to find the best one:

a) Delete perl from /opt/local/bin
b) Put /opt/local/bin at the end of the PATH 
c) Change gitweb-lib.sh to set up the PATH to /usr/bin, because that is what the
file gitweb_config.perl generated by gitweb-lib.sh expects.
