#### Description

The purpose of this pull request is to allow, when generating rpm's, the possibility of history/autocomplete to be seen in the interactive mode of kamcmd.

The proposed solution is to ensure that the readline-devel library is a requirement when building Kamailio, thus ensuring that kamcmd is compiled with this library.

Currently the specfile has as BuildRequires, the pkgconfig library. This library is installed by the readline-devel library (via ncurses-devel dependency), i.e. all existing logic remains unchanged. Furthermore, the readline-devel library is accessible on all distros that use this specfile, namely: Centos, Fedora, OpenSuse, RedHat.

Initially in my testing, I thought I needed to change the Makefile of kamcmd to look at mock path’s (find path of readline.h), but this is not necessary (at least in CentOS).

The possibility of adopting this solution in later branches would be useful, especially in the case of branch 5.6.1.

The tests were performed in a CentOS 7 environment (docker image), following the usual process for generating the rpm's (make rpm). This solution was tested on branch 5.5.4 and on master. In both cases, the history/autocomplete is successfully visible in the interactive mode of kamcmd.

```Shell Script [root@kamailio-build kamailio]# cat /etc/centos-release CentOS Linux release 7.9.2009 (Core) [root@kamailio-build kamailio]# uname -a Linux kamailio-build 5.10.124-linuxkit #1 SMP PREEMPT Thu Jun 30 08:18:26 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux ``` I would appreciate if you could evaluate this solution, since the presence of the autocomplete in kamcmd is very useful. Feel free to adopt changes to the proposed solution.
