Marco Casaroli 4db7594eb6 libs/libc/elf: Read the dynamic relocations at their file offset.
DT_REL and DT_JMPREL hold the link-time address of their table, and the
loader read the table at that value as a file offset.  The two are equal
only when the segment that holds it starts at file offset 0.  An object
linked with its text at file offset 0x1000, as the tree's gnu-elf.ld does,
had its relocations read from padding, so none were applied and the
module called through unrelocated pointers.

Translate the address through the PT_LOAD headers first.
