Modifies makefile uname system call directive from '-a' to '-o' to allow for reproducible output

Hello, I am posting this report to further the agenda of reproducible builds (wiki.freebsd.org/ReproducibleBuilds)

In this particular port, a system call, 'uname -a' is generating non-deterministic output on some builds with differing timestamps and node names.

A remedy is attached, changing the directive from -all to --operating-system allows this port to build in a reproducible fashion.

  astro/astrometry: Remove a source of non-reproducibality

  uname -a generates non-deterministic output on some hosts.  It's
  used when generating report.txt which is just documentation, so
  just don't call it.

uname -o is the same as uname -s and also not available on DragonFly, so
I've just removed uname -a instead.
