[libc] Wrong dependencies naming for many targets in libc

[bassiounix]

These are the tests being preventing from building because of wrong listing of dependencies names which does not exists anymore (some of them are renamed)

• Skipping unittest libc.test.src.__support.RPC.rpc_smoke_test.__unit__ as it has missing deps: libc.src.__support.RPC.rpc.
• Skipping hermetic test libc.test.src.__support.RPC.rpc_smoke_test.__hermetic__ as it has missing deps: libc.src.__support.RPC.rpc.
• Skipping unittest libc.test.src.time.clock_getres_test.__unit__ as it has missing deps: libc.src.time.clock_getres.
• Skipping hermetic test libc.test.src.time.clock_getres_test.__hermetic__ as it has missing deps: libc.src.time.clock_getres.
• Skipping unittest libc.test.src.sys.epoll.linux.epoll_pwait2_test as it has missing deps: libc.src.sys.epoll.epoll_pwait2.
