File libjpeg-ocloexec.patch of Package libjpeg62-turbo

This patch causes libjpeg to open all files with O_CLOEXEC
the "e" fopen mode is a glibc/linux specific feature hence
not suitable for other OS.

Note that it is NOT HANDLED GRACEFULLY on kernels older than 
2.6.23 or glibc < 2.7.x and WILL segfault.

The other alternative, using fcntl with FD_CLOEXEC is NOT
enough to prevent race conditions.
