Subject: [PATCH] fix(cronmaster): fix unexpected EOF in update_cronmaster
 script (#14411)

The heredoc used <<EOF (unquoted), causing the \ inside it
to be executed during installation. This embedded the entire cronmaster.sh
source (~250 lines) into the update script, which contained backtick-style
constructs that caused 'unexpected EOF while looking for matching backtick'
at line 44 when the update script was later run.

Use <<'EOF' so the literal \ text is written to the file.
