Robert Clausecker 903cb811ff lib/libc/amd64/string: add strlcpy scalar, baseline implementation 
Somewhat similar to stpncpy, but different in that we need to compute
the full source length even if the buffer is shorter than the source.

strlcat is implemented as a simple wrapper around strlcpy.  The scalar
implementation of strlcpy just calls into strlen() and memcpy() to do
the job.

Perf-wise we're very close to stpncpy.  The code is slightly slower as
it needs to carry on with finding the source string length even if the
buffer ends before the string.
