libcap: add menu entry to install tools.

Browse Source 
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.]

Install setcap, getcap, getpcaps and capsh tools.
For these tools to run properly, you should enable, in your
kernel configuration, extended file attributes/security labels
support for the file system type used on target system (e.g.
CONFIG_EXT2_FS_XATTR and CONFIG_EXT2_FS_SECURITY for ext2).
