[PATCH] tests: ptrace-sync: relax breakpoint pattern matching

In some OS distributions, the gdb output of the break instruction
doesn't contain the function name where the breakpoint is set. This
is observed on Ubuntu 22.04.5. with GNU gdb
(Ubuntu 12.1-0ubuntu1~22.04.2) 12.1., causing pattern matching
failures and subsequent test failures.

Remove the ": bp\." suffix requirement to make the pattern
more robust across different gdb versions and configurations.

The original failed log (run with -v) -

"
-> {{ "b bp" }}
EXPECT {{ ^Breakpoint 1 at .*: bp\.}}
<- {{ "Breakpoint 1 at 0x28b9: file ../tests/ptrace-sync.c, line 59." }}
<- {{ "(gdb)" }}

<timeout waiting for gdb>
"
