bug#36329: 26.2; file-size-human-readable issues

[Pierre Neidhardt]

I could spot 2 issues with file-size-human-readable:

1. Trailing ".0".  Compare

--8<---------------cut here---------------start------------->8---
(file-size-human-readable 2047)
"2.0k"
(file-size-human-readable 2048)
"2k"
--8<---------------cut here---------------end--------------->8---

2. Spurious "i" in 'iec mode for bytes:

--8<---------------cut here---------------start------------->8---
(file-size-human-readable 1 'si)
"1"
--8<---------------cut here---------------end--------------->8---
