libtevent: fix pyext_PATTERN for cross compilation

The pyext_PATTERN will add native arch as suffix when cross compiling.
For example, on qemuarm64, it is expanded to:
pyext_PATTERN ='%s.cpython-310-x86_64-linux-gnu.so'
which will result in the incorrect library name.

root@qemuarm64:~# find /usr/lib/python3.10/ -name \*tevent\*.so
/usr/lib/python3.10/site-packages/_tevent.cpython-310-x86_64-linux-gnu.so
/usr/lib/python3.10/site-packages/_tevent.so

Set pyext_PATTERN to '%s.so' to remove the suffix.
After the patch:
root@qemuarm64:~# find /usr/lib/python3.10/ -name \*tevent\*.so
/usr/lib/python3.10/site-packages/_tevent.so
