[Bug 1917539] [NEW] /usr/share/initramfs-tools/hooks/lvm2 is not executable

[Eugene Crosser]

Public bug reported:

after a recent (yesterday/today) upgrade of hirsute, it could not boot
from LUKS root, dropping to inirtamfs. Investigation showed that `lvm`
binary is not present in initramfs generated by initramfs-tools. When I
ran `initrmfs-tools` by hand with `-v` option, I noticed the message:

/usr/share/initramfs-tools/hooks/lvm2 ignored: not executable

(this message does not show up when initramfs-tools is run without `-v`)
Sure enough, after manually changing permissions to all-executable and rerunning initramfs-tools the binary is included in initrd and system boots normally.  But reinstalling lvm2 resets permissions again:

$ ls -l /usr/share/initramfs-tools/hooks/lvm2 
-rw-r--r-- 1 root root 691 Feb  8 16:25 /usr/share/initramfs-tools/hooks/lvm2

and on the next build, initrd does not contain lvm binary again.
