elf, uapi: Remove struct tag 'dynamic'dynamic
Such a generic struct tag shouldn't have been exposed in a public
header. Since it's undocumented, we can assume it's a historical
accident. And since no software (at least on Debian) relies on this
tag, we can safely remove it.
Here are the results of a Debian Code Search[2]:
$ # packages that contain 'include [<"]linux/elf\.h[">]'
$ curl -s https://codesearch.debian.net/results/e5e7c74dfcdae609/packages.txt > include
$ # packages that contain '\bstruct dynamic\b'
$ curl -s https://codesearch.debian.net/results/b23577e099048c6a/packages.txt > struct
$ cat struct include | sort | uniq -d
chromium
hurd
linux
qemu
qt6-webengine
qtwebengine-opensource-src
$ # chromium: Seems to hold a copy of the UAPI header. No uses of the tag.
$ # hurd: Same thing as chromium.
$ # linux: :)
$ # qemu: Same thing as chromium.
$ # qt6-webengine: Same thing as all.
$ # qtwebengine-opensource-src: Yet another copy.
