[LTP] [PATCH 1/1] df01.sh: Fix DF_FS_TYPE assignment on bind mount

[Petr Vorel]

In case of bind mount of testing directory, grep will assign filesystem
twice, with new line:

$ echo "DF_FS_TYPE: '$DF_FS_TYPE'"
DF_FS_TYPE: 'ext2
ext2'

Limiting only first line to avoid failure with confusing message:

df01 5 TFAIL: 'df' failed.
df: ext2: No such file or directory
