    tools/thermal: Fix possible path truncations

    A build with -D_FORTIFY_SOURCE=2 enabled will produce the following warnings:

    sysfs.c:63:30: warning: '%s' directive output may be truncated writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-truncation=]
      snprintf(filepath, 256, "%s/%s", path, filename);
                                  ^~
    Bump up the buffer to PATH_MAX which is the limit and account for all of
    the possible NUL and separators that could lead to exceeding the
    allocated buffer sizes.

    Fixes: 94f69966 ("tools/thermal: Introduce tmon, a tool for thermal subsystem")
