cap getdents length argument to INT_MAX
...
the linux syscall treats this argument as having type int, so passing
extremely long buffer sizes would be misinterpreted by the kernel.
since "short reads" are always acceptable, just cap it down.
patch based on musl commit 3d178a7e2b75066593fbd5705742c5808395d90d

zero initialize target
...
Fixes glibc_version being set to garbage. I've made this mistake
before so this is an attempt to prevent future bugs. Zig doesn't
have zero-initialization, so are we being a hypocrite by using this
C feature? No, because C doesn't have the feature that forces you to
initialize all fields. That would have prevented this bug every single
time.

add an update_glibc tool, delete dummy libc files
...
This is the beginning of supporting minimum GLIBC version as part of the
target. See #2509 for the motivation.
The dummy libc zig files are removed. A future commit will build them
on-the-fly, using the generated text files generated by the new tool,
which are checked into source control and distributed along with zig.
These generated text files are, together, 142KB (20KB gzipped).
Compare that to a naive bundling of the .abilist files, which would be
2.2MiB (375KB gzipped).
This is based on glibc 2.29.

The original issue that #2445 wanted to fix was solved in the previous
commit. However it also exposed the subsystem in the standard library,
which is still useful. So that's done in this commit, and #2445 can be
closed.
