Bug/rdkb 65469 bootstrap fix

[Suganya-Sugumar]

Added code changes to regenerate bootstrap.json if /nvram/bootstrap.json and /opt/secure/bootstrap.json are both empty. This is to address the issue reported in https://ccp.sys.comcast.net/browse/RDKB-65469.

Changes:

• Updates bootstrap recovery path to initialize bootstrap when /nvram/bootstrap.json exists but is empty.
