Revert "Other minor dependencies updates in 7.1.x patch"

This reverts commit 5a5f544a48.

Rationale: base64-js update in 5a5f544 causes extra
base64-js version to be installed under plist
(node_modules/plist/node_modules/base64-js),
which would need to be committed to satisfy the needs
of the deprecated Node.js 4 version.

The extra base64-js version in
node_modules/plist/node_modules/base64-js
was missed at the time 5a5f544 was committed.

The base64-js update in 5a5f544 is now deemed as
not wanted due to the extra base64-js version that
would need to be committed.

The other dependencies updates in 5a5f544
may be nice to have but not considered necessary
for the patch release.

Reverting now to unblock the upcoming 7.1.4 patch release.

Note that neither 5a5f544 nor this revert will
show up in the master branch.

 ## Functions
 
-All methods and classes take a final `options` object argument.  All
-options in this object are `false` by default.  The options supported
-are:
-
-- `loose`  Be more forgiving about not-quite-valid semver strings.
-  (Any resulting output will always be 100% strict compliant, of
-  course.)  For backwards compatibility reasons, if the `options`
-  argument is a boolean value instead of an object, it is interpreted
-  to be the `loose` param.
-- `includePrerelease`  Set to suppress the [default
-  behavior](https://github.com/npm/node-semver#prerelease-tags) of
-  excluding prerelease tagged versions from ranges unless they are
-  explicitly opted into.

 Strict-mode Comparators and Ranges will be strict about the SemVer
 strings that they parse.
