package/c-periphery: bump version to 2.2.1

Since commit "cmake: add cmake build support"
(https://github.com/vsergeev/c-periphery/commit/952e1e906a5d65b78932128af24b7dbb8cce2e9dvsergeev/c-periphery@d0a973c),
c-periphery implement cmake build, so use cmake-package instead of
generic-package. Due to this, it now builds a shared library, so we
drop the INSTALL_TARGET = NO.
