tf-cov-make: avoid usage of parenthesis with local variable

For bash'ism $(..) is command substitution method so output of
command is substituted, here to determine output of the command
subshell maybe used and thus can lead to not able to resolve local
variables if they are used inside parenthesis.

Use braces {..} as its a parameter expansion and doesn't involve
subshell.

The issue is observed in this job[1]:
