HV: elf_loader: Fix copy gpa bug in load elf32 

The elf images can't be loaded correctly because
the elf_loader copy_to_gpa with wrong size.
The p_filesz and p_memsz both belong to elf32_prog_entry,
this data structure describes segments loaded in ram.
p_filesz means size of segment in file and p_memsz
means size of segment in memory.
ELF loader should copy elf_img to gpa with the
size of p_prg_tbl_head32->p_filesz.

Tracked-On: #8642
