testsuite: Add filter for target socket support

The new analyzer tests for sockets are failing on embedded targets.
The newlib and avr-libc C libraries do not support sockets.

Testing done:
  - No changes in gcc.sum for x86_64-pc-linux-gnu, with or without this
    patch.
  - Filtered cases are now UNSUPPORTED instead of failing on AVR and PRU
    backends.

	* doc/sourcebuild.texi (sockets): Document new check.
