  1. sysctl: Remove fs.inotify.max_user_watches 

    This is already set by Arch via `/usr/lib/sysctl.d/10-arch.conf` from the `filesystem` package.

  2. sysctl: Remove increased max connections 

    According to [Arch Wiki](https://wiki.archlinux.org/title/Sysctl#Increase_the_maximum_connections) this only helps
on high-loaded servers. Desktops won't become high-loaded servers ever probably, so on the basis of that knowledge remove this.

If increasing this value does indeed has tangible benefits, I can revert this.

  1. sysctl: Do not set TCP Congestion Control Algorithm 

    We already have this set in the kernel, and having a duplicate here can cause instances when users want to test
the default algorithm in another kernel, but will still have BBR set.

  2. sysctl: Remove vm.dirty_expire_centisecs 

    This has always been commented. Even if not, the value set is the same as the kernel default. Unless we want
to tweak the value, keeping this here is redundant.

  1. sysctl: Remove net.ipv4.tcp_syncookies 

    This is the default value. No reason to enforce a default, especially if its in a package where it can be
overrided anyway from /etc or from cmdline.
