dbwrap: Pass "value" to dbwrap_do_locked() callback
I want to reduce dbwrap_record_get_value(). It makes the caller believe it can
make a copy of the TDB_DATA returned and that the value remains constant. It's
not, as you can always do a dbwrap_record_store().
This patch removes one requirement for getting the value out of a
db_record via dbwrap_record_get_value(). You can still make a copy, but from an
API perspective to me it's more obvious that "value" as a parameter to the
callback has a limited lifetime.

As these are not tested in selftest so any change would also be
untested. Of course they probably should be added in a different
MR.
Also not modified (because they are not tests, nor part of the
build system) are:
- smb2mount
- notifydd
- log2pacp
- debug2html
- smbfilter
- destroy_netlogon_creds_cli
- spotlight2*
- tevent_glib_tracker
These do however appear to be untested.
For now, the source4 forked client tools are left unchanged:
- smbclient4
- nmblookup4
Finally, the heimdal binaries are left as install=False as
they are either part of the build system or end-user tools
that we just don't want to install. These are however tested.
There are likely other platforms or build environments where building
our test binaries is more pain than valuable, see for example also
