evemu: bump version to 2.1.0

See [1] for details.

Change download url and source package format to enable usage of
upstream provided hash values.

Patches
- evemu-0001-SYN_MAX.patch
- evemu-0003-make-event-names-use-input.h-from-sysroot-instead-of.patch
are obsolete as there is no more host side python script for event name generation.

Patches
- evemu-0002-configure.ac-add-disable-tests-option.patch
- evemu-0005-configure.ac-add-disable-python-bindings-option.patch
are committed upstream.

[Thomas: drop EVEMU_AUTORECONF = YES, since we're now using a tarball
that has the configure script already generated, and we no longer have
patches touching the configure.ac/Makefile.am]
