This is a followup to CL 181278 and CL 181177.
According to cmd/go/testdata/script/README:
Each line is parsed into a sequence of space-separated command words,
with environment variable expansion and # marking an end-of-line comment.
Adding single quotes around text keeps spaces in that text from being treated
as word separators and also disables environment variable expansion.
We want $HOME to be expanded, so leave it out of the single-quoted
block of text.
I tested this change on macOS, and it makes TestScript/env_write pass.
Fixes #32503
