OK, I moved it to sysdeps/unix/sysv/linux/aarch64/.

OK, I updated install.texi, INSTALL, vlset.py doc part as well as commit message
such as the followings or my github [1].

[commit message] aarch64: Added Vector Length Set test helper script
This patch is a test helper script to change Vector Length for child
process. This script can be used as test-wrapper for 'make check'.
Usage examples:
~/build$ make check subdirs=string \
test-wrapper='~/glibc/sysdeps/unix/sysv/linux/aarch64/vltest.py 16'
~/build$ ~/glibc/sysdeps/unix/sysv/linux/aarch64/vltest.py 16 \
make test t=string/test-memcpy
~/build$ ~/glibc/sysdeps/unix/sysv/linux/aarch64/vltest.py 32 \
./debugglibc.sh string/test-memmove
~/build$ ~/glibc/sysdeps/unix/sysv/linux/aarch64/vltest.py 64 \
./testrun.sh string/test-memset
