[Buildroot] [PATCH] libcap: Add optional support for libattr capabilities

[Markos Chandras]

From: Markos Chandras <markos.chandras at imgtec.com>

libcap can optionally link to libattr to support extra
file capabilities. Link to this library and pull it as
dependency if BR2_PACKAGE_ATTR is selected.
