the (glibc) regexp engine used by Guile would either 1. stop scanning the
string or 2. crash with the error "string contains #\\nul character",
depending on the locale used.

This change works around this limitation by first replacing the NUL character
by an unused Unicode code point, doing the substitution, then reverting the
replacement.

* guix/build/utils.scm (unused-private-use-code-point)
(replace-char): New procedures.
(substitute): Make use of the above procedures to work around the NUL
character regexp engine limitation.
* tests/build-utils.scm: Add tests.
