[Buildroot] [PATCH v2] libcap: Add optional support for libattr capabilities

[Markos Chandras]

From: Markos Chandras <markos.chandras@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.

Buildroot uses a global namespace, so I renamed this to
LIBCAP_HAVE_LIBATTR and committed, thanks.
