Revert "osmo-config-merge: Add manual page"

This reverts commit 6dd00d876e2b947e070f776f90fbb8305a237d21.

Unfortunately, it seems older a2x versions don't support "-D" for
manpage generation:

All the osmocom master builds started to fail with:

make[2]: Entering directory '/build/deps/libosmocore/man'
a2x --doctype manpage --format manpage -D . osmo-config-merge.adoc
a2x: WARNING: --destination-dir option is only applicable to HTML based outputs
a2x: ERROR: "xmllint" --nonet --noout --valid "/build/deps/libosmocore/man/osmo-config-merge.xml" returned
non-zero exit status 127
Makefile:545: recipe for target 'osmo-config-merge.8' failed

-=====================
-
-NAME
-----
-osmo-config-merge - Merge osmocom config snippets into an existing config
-
-SYNOPSIS
---------
-[verse]
-*osmo-config-merge* <config-file> <config-patch> [--debug]
-
-DESCRIPTION
------------
-This utility allows you to merge an incremental config "patch"
-into an osmocom-style config file.
-
-The patch file follows the same syntax as the original config file.
-
-It works by appending the leaf nodes of the patch file to the respective
-nodes of the input config file.
-
-This process allows configuration file changes/updates to be performed
-in a more stable/reliable way than by means of (unified) diff files,
-as they break every time the context lines break.
-
-osmo-config-merge doesn't suffer from this problem, as it understands
-the tree-like nature of VTY config files.
-
-The resulting config is printed to stdout.
-
-NOTE: This only works with configuration files that have proper
-indenting, i.e. every level in the hierarchy must be indented excatly
-one character, not multiple.
-
-OPTIONS
--------
-*--debug*::
-	Show debugging output when parsing the config tree. Needs to be the last argument.
-
-EXAMPLE USAGE
--------------
-[verse]
-$ osmo-config-merge osmo-msc.cfg.base osmo-msc_change_network.cfg > osmo-msc.cfg
-
-EXIT STATUS
------------
-Exit status is 0 if the command was successful, and 1 in case of a
-wrong/missing argument. If the tool detects an error in the patch file the
-exit status is 2.
-
-SEE ALSO
---------
-The official Osmocom documentation including the VTY config refernce can be
-found at: http://ftp.osmocom.org/docs/latest/
-
-The Osmocom wiki is located at: http://projects.osmocom.org/
