Replace `...` with $(...)

Shellcheck warns that backticks are deprecated, so replace
them with the more modern $(...) syntax.

This patch has been generated automatically with this shell
command:
    perl -i -ape 's/`\(([^()`]*)\)`/\$($1)/; s/`([^(][^`]*)`/\$($1)/' *.sh lib/*.sh

This leaves two more `...` in test.sh which will be replaced by
hand in a later patch.
