cmd/geth: fix IPC probe in les test (#23094)

Browse Source 
Previously, the test waited a second and then failed if geth had not
started. This caused the test to fail intermittently. This change checks
whether the IPC is open 10 times over a 5 second period and then fails
if geth is still not available.
