We make lib{mach,hurd}user.so only call __mig_strlen which can be
relocated before libc.so is relocated, similar to what is done with
__mig_memcpy.

Why doing so? For memcpy we have glibc's
sysdeps/mach/include/mach/mig_support.h #define memcpy to __mig_memcp
Dynamically sized strings can be represented as c_string[*] (*). We inline
up to 64 bytes but can pass arbitrary strings if needed out of line. Currently
implementation is limited to input arguments only (MiG will error out if
used as output).
In the user stub, we first run mig_strlen on the param

Other pthread symbols are to move to libc.so too, to align on the move
that was done on Linux.
