libcap: add menu entry to install tools.
libcap provides a set of tools to manipulate capabilities, among which `setcap(8)` and `getcap(8)`. A new menu entry has been added to install them. [Thomas: mark the new option as requiring MMU support, because the programs use fork(), and completely rework the new .mk logic as it wasn't taking into account the BR2_PREFER_STATIC_LIB case.] Signed-off-by: Eric Le Bihan <eric.le.bihan.dev@free.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Install setcap, getcap, getpcaps and capsh tools.

For these tools to run properly, you should enable, in your

support for the file system type used on target system (e.g.
