[PATCH] sign-file: fix the perl warning message when extracting ASN.1

[Lee, Chun-Yi]

There have the following warning message when running modules install for sign ko files:

# make modules_install
...
  INSTALL drivers/input/touchscreen/pcap_ts.ko
Found = in conditional, should be == at scripts/sign-file line 164.
Found = in conditional, should be == at scripts/sign-file line 161.
Found = in conditional, should be == at scripts/sign-file line 159.

This patch change replace '=' by '==' in elsif conditions for avoid the above warning messages.
