Florian Fainelli bd1ebcbbf0 tools/thermal: Fix possible path truncations
[ Upstream commit 6c58cf40e3 ]

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.
