ci(e2e): collapse Android retry loop onto one line

The reactivecircus emulator-runner action runs each newline-separated
line of `script:` as a separate `sh -c` invocation. The YAML folded
scalar (>-) only collapses lines that share indentation; my retry
for-loop had deeper-indented body lines, so YAML preserved those
newlines and sh saw `... do` with no `done` -> Syntax error.

Put the entire `for/do/done` retry chain on one logical line so the
folded scalar produces a single sh command.
