[LU-7722] Install/uninstall of Lustre RPMs is slow due to regenerating of initramfs

Description

In the scripts of Lustre RPMS, weak-modules command is run. And in that command, dracut regenerates initramfs. Unfortunately, this process is very slow.

However, in most of cases, Lustre modules are not necessary for initramfs.
Thus, regenerating initramfs in scripts of RPMs is a waste of time, especailly for developers, since they need to install/uninstall RPMs frequently.

With the --no-initramfs, installing/uninstalling luster-module RPM speeds up a lot:
RPM Install Uninstall
--no-initramfs 6.852s 4.867s
Origin 2m48.694s 2m6.769s
