tool_cb_wrt: fix variable shadowing warning

Browse Source 
GCC 4.4 complains:
tool_cb_wrt.c:81: error: declaration of ‘isatty’ shadows a global
declaration
/usr/include/unistd.h:782: error: shadowed declaration is here

Fix this by renaming the variable.

Closes https://github.com/curl/curl/pull/1661
