Fixed capabilities version.
Previously, capset(2) was called with the 64-bit capabilities version
_LINUX_CAPABILITY_VERSION_3. With this version Linux kernel expected two
copies of struct __user_cap_data_struct, while only one was submitted. As a
result, random stack memory was accessed and random capabilities were requested
by the worker. This sometimes caused capset() errors. Now the 32-bit version
_LINUX_CAPABILITY_VERSION_1 is used instead. This is OK since CAP_NET_RAW is
a 32-bit capability (CAP_NET_RAW = 13).
