Fixes warning when redefining PATH_MAX when building with MINGW.

Fixes warning thrown when compiling digest.cc with MinGW64, by only defining PATH_MAX, if it has not yet been defined.
Else building with MinGW64, throws the following warning:

<PATH_TO_SOURCE_FOLDER>\boringssl\src\tool\digest.cc:39: warning: "PATH_MAX" redefined
   39 | #define PATH_MAX MAX_PATH
