tools/lib/lockdep: Add missing declaration of 'pr_cont()'
Commit:
681fbec881de ("lockdep: Use consistent printing primitives")
has moved lockdep away from using printk() for printing.
The commit added usage of pr_cont() which wasn't wrapped in the
userspace headers, causing the following warning for the
liblockdep build:
../../../kernel/locking/lockdep.c:3544:2: warning: implicit declaration of function 'pr_cont' [-Wimplicit-function-declaration]
Adding an empty declaration of 'pr_cont' fixes the problem.
