Improved the capabilities feature detection.
Previously included file sys/capability.h mentioned in capset(2) man page,
belongs to the libcap-dev package, which may not be installed on some Linux
systems when compiling nginx. This prevented the capabilities feature from
being detected and compiled on that systems.
Now linux/capability.h system header is included instead. Since capset()
declaration is located in sys/capability.h, now capset() syscall is defined
explicitly in code using the SYS_capset constant, similarly to other
Linux-specific features in nginx.
