Updating devel/p5-IPC-System-Simple from 1.18 to 1.20

Upstream changes:
1.20  Sat Jan  9 15:08:41 AUSEST 2010
        * TEST: t/win32.t no longer claims to have more tests than
          it really has.  This fixes an install issue under Windows.
          RT #53124.  Thanks to Erez Schatz and Curtis Jewell for
          spotting this.

1.19  Fri Dec  4 14:14:25 AUSEST 2009
        * TEST: Added tests to ensure correct behaviour when
          calling commands in Windows which are contained in directories
          that contain spaces. (These tests are currently skiped,
          as they're testing for a known bug.)
        * BUGFIX: Spurious warnings about redefining POSIX macros
          no longer plague Windows systems.
