package/libseccomp: bump version to 2.2.0

- change upstream URL, project moved to github
- removed patches not needed anymore since project switched to autoconf
- add newly supported platforms to Config.in

[Thomas:
 - remove hash file, since we're fetching from github now.]

-Subject: [PATCH] Remove the dependency on /proc
-
-The Makefile relied on a broken logic for the INSTALL_PC_MACRO.
-It was used like this: $(INSTALL_PC_MACRO) file.
-
-The INSTALL_PC_MACRO was then expanded with a trailing sharp, to pass
-the name of the file to install as a comment at the end of the command.
-
-And then, to retrieve the file to copy, it used the $NF variable of awk
-on the /proc/self/cmdline file to happily reinvent the argument
-mechanism.
-
-This patch removes of this crazy stuff by using the -t option of
-install, that keeps the same calling convention.
