[PATCH v2 4/7] fixup! reftable: add dump utility

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

avoid _XOPEN_SOURCE redefinition in alpine by making sure git-compat-util.h
is included first (as recommended in CodingGuidelines) and therefore avoid:

  In file included from ./hash.h:4,
                   from reftable/dump.c:19:
  ./git-compat-util.h:147: warning: "_XOPEN_SOURCE" redefined
    147 | #define _XOPEN_SOURCE 600 /* glibc2 and AIX 5.3L need 500, OpenBSD needs 600 for S_ISLNK() */
        |
  In file included from /usr/include/unistd.h:8,
                   from reftable/reftable-writer.h:15,
                   from reftable/dump.c:14:
  /usr/include/features.h:16: note: this is the location of the previous definition
     16 | #define _XOPEN_SOURCE 700
        |
