Lars Volker ffe3e47865 Only use O_CLOEXEC on platforms that support it 
Change a9fca58 made use of the O_CLOEXEC flag, which is not supported on
older Linux kernels. This change makes the use contingent on kernel
support.

Testing: I manually compiled breakpad on CentOS 5.8 running kernel
2.6.18-308.8.2.el5.centos.plusxen.
