Update to 4.54
Remove the patch which fixed upstream

Upstream changes:
4.54 Tue Aug 14 13:54:48 CEST 2018
        - include sys/mkdev.h or sys/sysmacros.h if available.
        - further tweaks to configure invocation for systems requiring --rpath.
        - no longer rely on custom paths on win32 platforms.
        - try to work around buggy PAGESIZE macro on solaris.

4.53 Tue Aug 14 11:27:50 CEST 2018
        - add $Config{libs} to LIBS for configure, to work around systems
          with broken library dependencies (... openbsd).

4.52 Sun Aug 12 08:09:45 CEST 2018
        - config.h.in was missing in distribution.

4.51 Sun Aug 12 07:24:14 CEST 2018
        - complete rework of the autoconf framework: IO::AIO now uses its own
          config.h, separate from libeio, and tries to test the actual perl
          environment, not the standard system environment.
        - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
          stat functions.
        - removed non-portable C++ syntax from eio.c.
        - try to fix readdir tests on cygwin spuriously failing.

4.5  Wed Aug  1 00:23:55 CEST 2018
        - aio_mtouch touch all pages as requested, not just the first page in most cases.
        - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
          and MREMAP_FIXED.
        - add O_ACCMODE.
        - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
