[WRAPPER] wrapped ncurses curterm via set_curterm; add selinux symbol to (mkdir, find)

[yzewei]

The following are fixes for running Docker containers on box64:

Runtime Environment:

Hardware: loongarch64

Kernel: 6.6.0-130.0.0.107.loongarch64

box64: main

x86 container: debian:sid-slim

Specific modifications:

wrappedlibtinfo6:

GO added _nc_basename, _nc_is_abs_path, _nc_rootname, and use_tioctl.
GOM added _nc_tiparm, del_curterm, set_curterm, and setupterm.
DATAM added cur_term.
The above modifications are due to errors encountered during the clear/reset translation runtime.

cur_term, as a pointer to a TERMINAL type structure, needs to be encapsulated by DATAM. Because ncurses generally uses reentrant as a build parameter, the global symbol cur_term will not be updated. The actual pointer is stored in _nc_prescreen._cur_term or SCREEN->_term, and cur_term cannot be directly accessed. Therefore, a layout-matched TERMINAL shadow needs to be constructed.

wrappedselinux:

GO added setfilecon to fix missing symbols in the find function.
GO added context_free context_new context_str context_type_get context_type_set getcon_raw getfscreatecon_raw mode_to_security_class security_compute_create_raw ...

PTAL！

For Global symbol like NCurses uses, they are some limitation with box64 wrapping... So I have added some hack to workaround those limitation. Take a look at librarian/globalsymbols.c to see how they are handled. You'll see that cur_term is already there. But indeed, it's not wrapped in tfinfo6... so strange.

You should not need to DATAM(cur_term), like for the other global variables... But what be missing probably is the appropriate calls to my_updateGlobalTInfo(); and my_checkGlobalTInfo() at the right place, like with my6_initscr() for the ncurses6 version of it.

This can be resolved by pushing a new commit.
