perf tests: Rename trace+probe_libc_inet_pton to record+probe_libc_inet_pton
Because the test is no longer using perf trace but perf record instead.

-# probe libc's inet_pton & backtrace it with ping
-
-# Installs a probe on libc's inet_pton function, that will use uprobes,
-# then use 'perf trace' on a ping to localhost asking for just one packet
-# with the a backtrace 3 levels deep, check that it is what we expect.
-# This needs no debuginfo package, all is done using the libc ELF symtab
-# and the CFI info in the binaries.
