python-utils-r1.eclass: Add a verbose python_has_version() wrapper
Add a python_has_version() wrapper for convenient use
in python_check_deps(). It includes:
- verbose output
- default "-b" root that's more suitable for build-time checks
- forward compatibility for -b/-d/-r arguments in EAPI 6

+# @FUNCTION: python_has_version
+# @USAGE: [-b|-d|-r] <atom>...
+# @DESCRIPTION:
+# A convenience wrapper for has_version() with verbose output and better
+# defaults for use in python_check_deps().
+#
+# The wrapper accepts EAPI 7+-style -b/-d/-r options to indicate
+# the root to perform the lookup on. Unlike has_version, the default
+# is -b. In EAPI 6, -b and -d are translated to --host-root
+# for compatibility.
+#
+# The wrapper accepts multiple package specifications. For the check
+# to succeed, *all* specified atoms must match.
