delete getifaddrs

[robinyuan1002]

When I tried to fix the issue 20, I found out that getifaddrs is not a syscall but a glibc function instead. According to our disscussion, we decided to delete getifaddrs from Rawposix and handle rest of mechanism through fixing sockaddr data structure, which has been mentioned in issue #42

Could you add a description explaining the purpose of this change, where we previously discussed it? This will help provide context for future reference and make it clear why this modification was made.

I believe there is also getifaddrs test case in rawposix that should be deleted together. Specifically,

lind-wasm/src/RawPOSIX/src/tests/networking_tests.rs

Line 4272 in 540dec5

pub fn ut_lind_net_getifaddrs() {

Should this eventually get converted to an integration test where we actually run an app which calls this glibc function?

We've had that already: https://github.com/Lind-Project/lind-wasm/blob/main/tests/unit-tests/config_tests/non-deterministic/getifaddrs.c

@rennergade this PR is ready to merge.

I believe we should also get rid of the gen_netdevs files and the getifaddrs_from_file function in comm.rs even though its currently commented out.

FYI: gen_netdevs files files should locate on

src/RawPOSIX/gen_netdevs.c
src/RawPOSIX/gen_netdevs.sh

It seems like there are no getifaddrs_from_file function in comm.rs.

We can merge this once @qianxichen233 approves his change requests
