[BusyBox] [PATCH] compiler warning removal in strings.c

[Stewart Brodie]

This patch is to stop compiler warnings from miscutils/strings.c about
variables which may be used before being initialised.

The variable "string" is passed to free() but may not be initialised.  It may
not be possible to reach the free without initialising the variable but I
cannot be certain that my inspection of the code has not missed a
code path.  Initialising the value to NULL will remove any doubt.  The
variable "t" is now initialised to zero for safety.
