utils: add patch_fd() and patch_stdio() helpers
Introduce two new helper functions to deal with stdio redirecation in a
uniform, reliable manner:
The patch_fd() function will attempt to redirect the given fd number to the
specified file, using the supplied flags for the open() syscall. When the
device is NULL, "/dev/null" is asumed, when the device is a relative path,
openat() is used to open it relative to the "/dev" directory. When the device
cannot be openend, a fallback to "/dev/null" is attempted.
The patch_stdio() function is essentially a wrapper around patch_fd(),
providing an easy interface to redirect stdin, stdout and stderr to the same
given device.
Both function return 0 on success and -1 on error. The errno variable will
be set accordingly.

SECCOMP_FILTER isn't supported on ARM OABI.
Thus enable seccomp support in jail only for EABI.

The REG_SYSCALL macro seems to be an unused left-over.
However, it's defined for other architectures as well.

instance: handle setgid() before setuid()
When attempting to run a service with an unprivileged user and group
id procd, the following error might occur:
procd: failed to set uid:1000, gid:1000
This is due to the fact that procd first performs the setuid(), then
the setgid() call.
Usually there no sufficient permissions after a setuid() anymore to
change the effective group id of the process.
Refactor the code to:
* Swap the invocations (first gid, then uid)
* Don't set user or group id if it is 0
* Handle errors independently and make them more verbose
