Support full backups of /sdcard

[SamCyanide]

Hi,

Due to followLinks being False, running backups of /sdcard without specifying a deeper directory fails.

/sdcard/[directory] works fine, but it ignores /sdcard due to it being a symlink.

python adbsync.py --pull --adb-flag a 'J:\GalaxyS10BackupsAug2021newer\Apr32022\sdcard\' /sdcard --exclude MyVerizon  --show-progress
[WARNING] Ignoring symlink '/sdcard'

Note:
A potential solution is to use /storage/emulated/0 instead, but sometimes the permissions for this directory do not work/are not set properly over ADB, causing a permission denied error. /sdcard seems to be more consistent, even if it is just a link.

Regardless, it seems there are some issues still with using that.

Huh UnicodeDecodeError that's a new one for adbsync lol. Perhaps it's to do with Windows using UTF-16 (or anything non-UTF-8) as its encoding? I'm running the same version of adb
