tree-wide: Switch tabs ⭾ in various files over to spaces ␠

As $DEITY intended.

I was reading the `prepare-root.c` code and the indentation damage was
distracting. Squash tabs that have leaked into various places in the code. I
didn't yet touch the `src/libostree` bits as that has higher potential for
conflict.

Closes: #852
