Also made the stack more configurable for netframe SR

version up also for some dependencies

Apache failed to compile in environments in which the `which` command
was not present (such as Docker).
This is fixed upstream (by using `command -v` instead) in
https://github.com/apache/httpd/commit/05297d7b00f0cb1f20d3ff14f4409097df2615fe
but not yet released.

This commit patches the configure script in a similar way, so that
the `which` command is not used.

This allows to run multiple test suites on the same instances,
each test suite will wait until the current one is done

Latest fix for SSB NR ARFCN computation is needed for bands such as N79

qmpbackup 0.43 was leaving temporary files instead of removing them leading to
filling up disk space of the machines.

Cover the situation in test and pick up fixed version qmpbackup 0.44

Put the decolorization directly in the generated binary.

We don't create new instances anymore because it is currently
not possible to add instance nodes with slapos python client.
We therefore use existing services but set all necessary
parameters on them before each test.

TODO:
 * start and stop the services on each test
 * add a lock to prevent multiple E2E tests running on the
   same machine

If libiconv is not linked to gettext, I get the following error during
the compilation of gcc-10.5 (in a system with minimal requirements):

```
INFO msgfmt -o de.mo ../../.././libstdc++-v3/po/de.po
INFO msgfmt: Cannot convert from "ISO-8859-1" to "UTF-8". msgfmt relies on iconv(). This version was built without iconv().
```
