support/dependencies/dependencies.sh: correct check for open perl module

Browse Source 
Commit 4cdd99190e (support/dependencies/dependencies.sh: require open perl
package for libxcrypt) added a check for the "open" perl module for
libxcrypt, but it does not work as "open" cannot be directly used with
"require" as an argument is needed:

perl -e "require open"
Not enough arguments for open at -e line 1, at EOF
Execution of -e aborted due to compilation errors.

So special case the check to instead check with "use open ':std'".
