xumia 7f78006224 [Bug][Build] Fix the variable patterns not replaced issue (#11572)
#### Why I did it

The %%EXTRA_CMDLINE_LINUX%% is not replaced to the real value, it has impact on the kernel parameter settings.
See the log sonic-vs.img.gz.log in the latest master build. In the grub.cfg, the %%EXTRA_CMDLINE_LINUX%% is set in the linux command line.
```
Installing for i386-pc platform.
Installation finished. No error reported.

EXTRA_CMDLINE_LINUX=%%EXTRA_CMDLINE_LINUX%%
