[PATCH v2 015/142] t0300-credentials.sh: use the $( ... ) construct for command substitution

The Git CodingGuidelines prefer the $( ... ) construct for command substitution instead of using the back-quotes, or grave accents (`..`).

The backquoted form is the historical method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. Because of this the POSIX shell adopted the $(…) feature from the Korn shell.

The patch was generated by the simple script
for _f in $(find . -name "*.sh")
do
  sed -i 's@`\(.*\)`@$(\1)@g' ${_f}
done
