    scripts/mksysmap: fix escape of '$' in the __pi_ pattern

    Commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed script")
    converted scripts/mksysmap from a shell script to a sed script.

    However an error was made - escaping of '$' required \\ escaping in shell
    but only \ in a sed script.

    This was mostly corrected in commit 7a6c355b55c0 ("scripts/mksysmap: Fix
    escape chars '$'"), but this fix missed arm64 PIE namespace local symbols
    like __pi_$x and __pi_$d which appear in System.map and /proc/kallsyms:

    $ grep __pi_\\$ /proc/kallsyms | sort -u
    0000000000000000 d __pi_$d
    0000000000000000 t __pi_$x

    Fix the escaping properly.
