Subject: perf genelf: Set ELF program header addresses properly
Git-commit: 1af478903fc48c1409a8dd6b698383b62387adf1
Patch-mainline: v6.8-rc1
References: git-fixes
The text section starts after the ELF headers so PHDR.p_vaddr and
others should have the correct addresses.
Fixes: babd04386b1df8c3 ("perf jit: Include program header in ELF files")
