Remove runtime managers since ti-core-initramfs does not requires

others.
I don't think this is going to pass muster. We just added those in to
make the initramfs function correctly with the rest of the system post
boot.
What is the more in depth reason you want to remove them? Are they
causing you a problem?
The aim is to reduce the size of the image further so that it can fit in
lesser memory devices like am62l(128MiB).
Since we do not require login support for the usecase of just probing
modules I removed the login manager here.
Similarly initramfs-udev will handle what we aim with this image instead
of having a runtime dev manager separately.
The change results in shrinking the image from 90MBs(20MBs compressed)
to about 25MB's (6-7 MBs compressed).

I'll let Denys chime in more since he did the work to figure out what
all we needed to add in to make it "correct".

This patch will help in reducing the size of the initramfs to about 7
MB's compressed and 25 MB's uncompressed
