nvim: Change lualine design

Slightly adapt lualine to not have arrow section/component dividers,
but simple slanted lines. Gets rid of a tiny bit of noise while still
clearly subdividing the sections for me which I need.

Also, removed displaying the hostname. I know which host I am on
generally, and rarely make use of it so it's just unnecessary info
for me.
