tests: add more mock wrappers

This change allows for tests to run when the compiler is inlining some
other interfaces.  This happens when compiling on the chromium chroot
environment.

* __fgets_chk() is being used instead of fgets() in
  get_max_kernel_buf_size() on linux_spi.c
* __vfprintf_chk() is being used instead of fprintf() in
  disable_power_management() on power.c
* __open64_2() is being used instead of open() in i2c_open_path() on
  i2c_helper_linux.c
