Subject: [PATCH] use more idiomatic/correct embedded shell scripting

Formatting arguments into code is fragile, and meson natively knows how
to pass files as arguments via argv. So pass them as arguments to the
shell.

Subject: [PATCH] remove pointless copying of files into build directory

I'm not entirely sure what this did, but it seems to be obsoleted by
commit 93bad825406d13ed5eb2cf27541dc58194bef8f3.
