fstrans: Remove unused foo() function

The point of it seems to have been to silence an unused function warning, but
there's no point if we're just transitioning that to another unused function
warning.

src/fc/fstrans.c:32:20: warning: unused function 'foo' [-Wunused-function]
static inline void foo(void) { (void) is_numeric("a"); }
                   ^
1 warning generated.
