nativesdk-binutils: correct path to ld.so.conf

The alternative ld.so patch is set up so the linker will search
the nativesdk sysroot before searching the host filesystem.

However the patch concatenates <sysroot>/etc and /etc/ld.so.conf
leading to a path that does not exist:

3061991 openat(AT_FDCWD, "/buildtools/sysroots/x86_64-pokysdk-linux/etc/etc/ld.so.conf",
O_RDONLY) = -1 ENOENT (No such file or directory)

In native-nspr, the build uses -lpthread, which triggers a search for librt, but because
of the above it drags in the system librt leading to errors as follows:

/buildtools/sysroots/x86_64-pokysdk-linux/usr/lib/gcc/x86_64-pokysdk-linux/
9.3.0/../../../../x86_64-pokysdk-linux/bin/ld: /lib64/librt.so.1:
undefined reference to `__clock_getcpuclockid@GLIBC_PRIVATE'

update concatenation to correctly construct the path to the nativesdk ld.so.conf

[YOCTO #13853]
