musl: add typedefs for Elf64_Relr and Elf32_Relr

The absence of this typedef causes elfutils to report the following error:
/usr/include/gelf.h:86:9: error: unknown type name 'Elf64_Relr'

+Subject: [PATCH] elf.h: add typedefs for Elf64_Relr and Elf32_Relr
+
+These were overlooked when DT_RELR was added in commit
+d32dadd60efb9d3b255351a3b532f8e4c3dd0db1, potentially breaking
+software that treats presence of the DT_RELR macro as implying they
+exist.
