Fix startup on MS-Windows when 'gdb.ini' is found in $HOME
* windows-nat.c (_initialize_check_for_gdb_ini): Fix off-by-one
error in allocation of space for "$HOME/.gdbinit" string. This
caused GDB to abort on startup whenever a '~/gdb.ini' file was
actually found, because xsnprintf would hit an assertion
violation.
