From: Pranit Bauva <pranit.bauva@xxxxxxxxx>
Removes the `static` keyword from `exists_in_PATH()` function
and declares the function in `run-command.h` file.
The function will be used in bisect_visualize() in a later
commit.
`exists_in_PATH()` and `locate_in_PATH()` functions don't
depend on file-local variables.
