tools/eclipse: mark --root as a required argument

argparse Arguments can be flagged as required. When missing,
parse_args() outputs an error message and exit 2 which we previously
handled with custom code.

Note the sys.exit(1) was never invoked since setting an error cause
argparse to exit immediately after printing the message.

Pass `required = True` to the root option and remove custom handling.

This also change the generated usage message slightly removing the
brackets surrounding `-r ROOT` to indicate it is required.

BEFORE

 $ ./tools/eclipse/project.py ; echo $?
 usage: Create Eclipse Project [-h] [-r ROOT] ...
 Create Eclipse Project: error: Root option not provided
 2

AFTER
 $ ./tools/eclipse/project.py ; echo $?
 usage: Create Eclipse Project [-h] -r ROOT ...
 Create Eclipse Project: error: the following arguments are required: -r/--root
 2
