p5-IO-AIO: update to 4.80.

4.80 Sat 01 Apr 2023 04:13:37 CEST
	- remove long obsolete "paths must be absolute" text in aio_open/stat
          descriptions.
	- another workaround for the low-quality musl libc.
	- test for umount seperately, as it is more portable.
        - some low-quality posix attempts (openbsd, osx) declare the availability
          of fexecve but then don't even bother to implemnent a stub.
