libroot: Use strnlen in strndup.
This is both more correct, as we need to not read past the 'size'
position of the passed pointer, and much faster, in the case where
the passed pointer is into some very large block of memory.
This provides an unbelievable speedup to a microbenchmark posted on IRC
that makes heavy use of this function in tandem with some rather
large allocations. (Some variants of it go from multiple minutes
to under a second!)
