Describe the bug
The symbols from system libraries such as libc are not properly imported into the profiling results.

To Reproduce
Steps to reproduce the behavior:

1. Do sudo apt install libc6-dbg and try to profile a code, which calls a libc function
2. Despite the debug information is available, the libc symbols will be shown "??" in hotspot (see screenshot)

Expected behavior
The actual libc symbol name is expected instead of ??

Version Info (please complete the following information):

• Linux Kernel version: 5.4.0
• perf version: 5.4.60
• hotspot version: AppImage
