fix: set DSG_DATA_DIRS for linglong compatibility

Added DSG_DATA_DIRS environment variable setting in both dde-dconfig-
editor and dde-dconfig main functions
The variable is set to include both standard path (/usr/share/dsg) and
linglong container path (/var/lib/linglong/entries/share/dsg)
This ensures dconfig applications can access configuration files in both
standard and linglong environments
Maintains compatibility with dde-dconfig-daemon which already uses this
environment variable

fix: 为玲珑兼容性设置 DSG_DATA_DIRS 环境变量

在 dde-dconfig-editor 和 dde-dconfig 的主函数中添加了 DSG_DATA_DIRS 环境
变量设置
该变量包含标准路径 (/usr/share/dsg) 和玲珑容器路径 (/var/lib/linglong/
entries/share/dsg)
确保配置应用程序能够在标准环境和玲珑环境中访问配置文件
与已使用此环境变量的 dde-dconfig-daemon 保持兼容性
