* gnu/packages/admin.scm (isc-dhcp): Update BIND version to 9.11.9.
[arguments]: In the 'replace-bundled-bind' phase, apply the patch.  In the
'post-configure' phase: Refine a substitute* regexp to avoid substituting an
instance of "./configure.log" in the BIND Makefile.  Substitute /usr/bin/file
in the BIND configure script.
[native-inputs]: Add 'file', 'patch', and the patch.
[inputs]: Update the hash of bind-source-tarball.
