[Buildroot] [PATCH 1/1] support/scripts/apply-patches.sh: manage uncompression

[Fabrice Fontaine]

Extract from bug report:

"Code line 120 to line 128 is to check whether the patch containing
"rename from" and "rename to". But it directly use grep to find,
ignoring the patch may be a tar file or else. It can only work on patch
of textfile form."

Fixes:
