platform-intel: fix buffer overflow

*** buffer overflow detected ***: terminated
Aborted (core dumped)
Issue is related to D_FORTIFY_SOURCE=3 flag and depends on environment,
especially compiler version. In function active_arrays_by_format length of
path buffer is calculated dynamically based on parameters, while PATH_MAX
is used in snprintf, this is my lead to buffer overflow.
It is fixed by change dynamic length calculation, to use define PATH_MAX
for path length.
