git-compat-util: work around fileno(fp) that is a macro
On various BSD's, fileno(fp) is implemented as a macro that directly accesses the fields in the FILE * object, which breaks a function that accepts a "void *fp" parameter and calls fileno(fp) and expect it to work. Work it around by adding a compile-time knob FILENO_IS_A_MACRO that inserts a real helper function in the middle of the callchain.
