change errno.h to cerrno

The former is deprecated by C++14. It's also functionally the same. From the standard: 19.4 The header<cerrno>is described in Table 43. Its contents are the same as the POSIX header<errno.h>,except that errno shall be defined as a macro. [Note: The intent is to remain in close alignment with the POSIX standard.] A separate errno value shall be provided for each thread. Signed-off-by: Rosen Penev <rosenp@gmail.com>
