configure.ac: fix building against BusyBox sed

Ratchanan Srirattanamet requested to merge personal/peat-psuwit/fix-busybox-sed into main

Welp, when you are not using -E (extended) mode, basic POSIX regex means that + doesn't have to be escaped. Escaping it confuses some version of sed, such as BusyBox sed in recent version of Alpine Linux which fails with sed: bad regex '\+': Repetition not preceded by valid expression.

POSIX regex, why do you have basic mode?

Fixes: #26 (closed)
