sanity.bbclass: handle lack of permission to read /proc/sys/vm/mmap_min_addr
* With 2.6.33-rc2-00252-ge9e5521 on my host I noticed that
"cat /proc/sys/vm/mmap_min_addr" returns now
"cat: /proc/sys/vm/mmap_min_addr: Operation not permitted"
Its probably becuse of
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0e1a6ef2dea88101b056b6d9984f3325c5efced3
But I'm not sure if checking CAP_SYS_RAWIO even for reading this value
is intentional or just bug which should be fixed in kernel.
This patch makes bitbake ignore reading error. Possible QEmu failure is not
handled yet.
