Build: Make the sed usage portable across Linux & macOSHEADmain

On macOS (which uses the BSD-variant of sed), the `-i` flag requires its
“backup extension” to come immediately after the i (with a space), even if
it’s empty; this made the release `sed` commands fail on macOS. The GNU sed
doesn’t require an extension but it allows it.

To make the commands work both on macOS & Linux, make the following changes:
1. Always specify the backup extension.
2. Explicitly specify the script part by using the `-e` flag.
3. To simplify the patterns, use `|` as a separator instead of `/`; then
   slashes don't need to be escaped in the script parts.
