enter_namespaces(): Fix uid/gid mapping
...
This was not caught before because a test was missing, fprintf() without ferror()
didn't help, and calling code did not depend on uid maps so far.
Add tests.

perform_mounts(): Fix potential leak and fix iteration
...
We would not free 'concat_path' in all potential paths.
Also, the iteration would not continue potentially.
This was case unlikely to be hit in practise.

exile_landlock_is_available(): Fix availability check
...
The check only assumed the existance of ABI version 1, which
is not the case any more.

Close file fds by default, introduce policy->keep_fds_open
...
The better default is to close them, not keeping them open.
Does not close sockets and pipes to not interfere with IPC.

check_policy_sanity(): Allow vows and syscall policies

Adjust checks to allow a mixed mode between syscall policies and vows.
Check for some easy to make mistakes in such scenario.

Introduce EXILE_SYSCALL_DENY_RET_NOSYS for syscalls like clone3()
...
clone3() is used more and more, but we cannot filter it. We can either
allow it fully or return ENONYS. Some libraries perform fallbacks to the
older clone() in that case, which we can filter again.

exile_flags_to_landlock(): Cover more with ALL_WRITE, except devices
...
More consistent with mount(), where MS_NODEV disallows those.
We may need to introduce a flag that simply allows everything

exile.h: Move definitions to new file exile.c
...
Especially with exile_launch(), we will be included
from more than one translation unit. Thus, ODR becomes
a headache now.
So move definitions to exile.c.
