new package: tinyramfs

[dkwo]

• I tested the changes in this PR: yes
• This new package conforms to the package requirements: yes
• I built this PR locally for my native architecture, (x86_64-musl)

one has to edit the config file; I did not add eudev, cryptsetup, etc to depends, as this can vary.

it works, with

$ cat /etc/tinyramfs/config 
compress="gzip -9"
hooks="eudev,luks,lvm"
hostonly=yes
luks_root="UUID=..."
luks_name=cryptroot 
luks_discard=yes
lvm_group=cryptroot 
lvm_name=root
root="UUID=..."

@ahesford do you think this could be added as a choice of initram? it has a small issue with modules (right now hostonly works though), but works just fine with luks, lvm (tested by me), zfs, various udev replacements (as per the homepage).
