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

Browse Source 
Commit b18b047002 ("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 7a6c355b55 ("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.
