[Tracking] Enable LTP tests after fixing sgx-lkl bugs

[hukoyu]

When failing LTP tests categorized, they were categorized into 4 categories:

1) Test Issues - Test Bugs:

• There is bug in the test code such as non-existing folder or user and so on
• Fix bug in test code and enable test

2) Test Issue – Test Using Not-Supported Feature

• Testing supported feature (syscall) in sgx-lkl but in the test code a not-supported feature is used
• Refactor test code without using not-supported feature and enable test

**3) Testing Not Supported Feature

• Sgx-lkl will not support these features due to limitations such as single process, single user
• We will disable these tests. They are not applicable since sgx-lkl doesn’t implement these features**

4) SGX-LKL Bug

• Tests are  legit and failures are genuine. Tests failing due to incomplete implementation or bug in sgx-lkl implementation.
• Fix bug in sgx-lkl and enable test

Currently there are 56 tests in "SGX-LKL Bug" category that we will track with this issue.
