Subject: [PATCH] Peg to updated t_cose version fc3a4b2c

The current version of TS fails to build due to a regression introduced
by a new t_cose version in the upstream project.
The issue is caused by the t_cose external component incorrectly using
tip of master as the upstream version id, which makes strict dependency
control impossible. Change the upstream version id to an SHA, to enable
controlling compatibility issues introduced by future upstream updates.

At the same time update the dependency to the current latest version.
The upstream project is now compatile with mbedtls 3.0.0 API changes
so the previously required compatibility patch has been removed.
