Fix accidental line wrapping introduced in r286122.

286122 by ed:
Limit rights on process descriptors.

On CloudABI, the rights bits returned by cap_rights_get() match up with
the operations that you can actually perform on the file descriptor.

Limiting the rights is good, because it makes it easier to get uniform
behaviour across different operating systems. If process descriptors on
FreeBSD would suddenly gain support for any new file operation, this
wouldn't become exposed to CloudABI processes without first extending
the rights.

Extend fork1() to gain a 'struct filecaps' argument that allows you to
construct process descriptors with custom rights. Use this in
cloudabi_sys_proc_fork() to limit the rights to just fstat() and
pdwait().

temporarily fix build..  This isn't the final fix, and testing is
still on going, but it has passed world for mips and powerpc...

I know this has an extra semicolon, but this is the patch that is
tested...

Looks like better fix is to use _Static_assert...
