perl: fix @INC, v2

From: Tom Zanussi <[email protected]>

This fixes the bug reported by Kang Kai in a way that allows perf scripting to continue to work.

Before this patch, @INC on the target would contain a native path:

@INC:

     /etc/perl
     /usr/lib/perl/site_perl/5.14.2/
     /usr/lib/perl/site_perl/5.14.2
     /usr/lib/perl/vendor_perl/5.14.2/
     /usr/lib/perl/vendor_perl/5.14.2
     /mnt/sda10/poky-all-platform/build-qemuppc/tmp/sysroots/qemuppc/usr/lib/perl/5.14.2/
     /usr/lib/perl/5.14.2
     /usr/local/lib/site_perl
     /usr/lib/perl/5.14.2
     .

Kang Kai's patch reverted the problem that caused the native path to appear, but also caused perf to report that scripting wasn't supported.

With this patchset, the native path is gone:

@INC:

    /etc/perl
    /usr/lib/perl/site_perl/5.14.2/
    /usr/lib/perl/site_perl/5.14.2
    /usr/lib/perl/vendor_perl/5.14.2/
    /usr/lib/perl/vendor_perl/5.14.2
    /usr/lib/perl/5.14.2/
    /usr/lib/perl/5.14.2
    /usr/local/lib/site_perl
    /usr/lib/perl/5.14.2
    .

and the perf Perl binding continues to work:

root@crownbay:~# perf script rwtop

read counts by pid:

pid comm # reads bytes_req bytes_read

------  --------------------  ----------  ----------  ----------
  1524  perf                        5629      213712      213648
  1508  dropbear                       8      131000         607

write counts by pid:

pid comm # writes bytes_written

------  --------------------  ----------  -------------
  1522  perf                          11         845320
  1508  dropbear                       8            944

Tested on qemux86 and crownbay.
