perf_counter tools: Adjust only prelinked symbol's addresses
I.e. we can't handle these two kinds of files in the same way:
1) prelinked system library:
[acme@doppio pahole]$ readelf -s /usr/lib64/libdw-0.141.so | egrep 'FUNC.+GLOBAL.+dwfl_report_elf'
278: 00000030450105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf@@ELFUTILS_0.122
2) not prelinked library with debug information from a -debuginfo package:
[acme@doppio pahole]$ readelf -s /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | egrep 'FUNC.+GLOBAL.+dwfl_report_elf'
629: 00000000000105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf
[acme@doppio pahole]$
Now the numbers I got for a pahole perf run are in line with
the numbers I get from oprofile.
