package/libcap: add patch to fix build on ARC, OpenRISC, Microblaze

Browse Source 
Following the bump of libcap to version 2.76 in commit
e2eb2ee58b, the build started failing on
ARC, OpenRISC, Microblaze. The bug was reported upstream at
https://bugzilla.kernel.org/show_bug.cgi?id=219915 and was
subsequently fixed by upstream commit:

  https://git.kernel.org/pub/scm/libs/libcap/libcap.git/commit/?id=7a2eee56607218d017af8d26c2c41dba83629708

Which we backport in this commit.

Fixes:

Subject: [PATCH] First attempt at PSX support for microblaze, arc and
openrisc.
I found some confusing macrology for openrisc. I'm optimistic that
this is recognized with the __or1k__ gcc macro.
See for details:
