perf unwind: Unwind with libdw doesn't take symfs into account
[ Upstream commit 3d20c62466
]
Path passed to libdw for unwinding doesn't include symfs path
if specified, so unwinding fails because ELF file is not found.
Similar to unwinding with libunwind, pass symsrc_filename instead
of long_name. If there is no symsrc_filename, fallback to long_name.
