Build still borken in vfs_syscalls

[Paul Goyette <paul%whooppee.com@localhost>]

"l" might not be used in rump, but it is used in standard kernels:

--- vfs_syscalls.o ---
/build/netbsd-local/src/sys/kern/vfs_syscalls.c: In function 'do_sys_rename':
/build/netbsd-local/src/sys/kern/vfs_syscalls.c:3287: error: 'l' undeclared 
(first use in this function)
/build/netbsd-local/src/sys/kern/vfs_syscalls.c:3287: error: (Each undeclared 
identifier is reported only once
/build/netbsd-local/src/sys/kern/vfs_syscalls.c:3287: error: for each function 
it appears in.)
