Fix "Remove tmp prefix from tar path"

[turuslan]

Fixes #158 and reverts #176.

I introduced bug by using unnecessary wildcard.
Fixed by removing it.

-    tar -czf $__tarball_output_path -C $__tmp_dir filcrypto/*
+    tar -czf $__tarball_output_path -C $__tmp_dir filcrypto

However code before #158 also had unnecessary wildcard.

-    tar -czf $__tarball_output_path $__tmp_dir/*
+    tar -czf $__tarball_output_path $__tmp_dir

There are two options for tar file structure:

1. One line change to just remove tmp prefix (sufficient)

-    tar -czf $__tarball_output_path $__tmp_dir/*
+    tar -czf $__tarball_output_path -C $__tmp_dir .

2. Remove tmp prefix and put files in a directory.
   This is just for conveniece - it's annoying when archive is unpacked in wrong directory, and it creates lots of files there, and it's not easy to write all the filenames for rm or mv - tar file can have single root directory.

+    mkdir $__tmp_dir/filcrypto
-    find -L . -type f -name filcrypto.h -exec cp -- "{}" $__tmp_dir/ \;
+    find -L . -type f -name filcrypto.h -exec cp -- "{}" $__tmp_dir/filcrypto \;
-    find -L . -type f -name libfilcrypto.a -exec cp -- "{}" $__tmp_dir/ \;
+    find -L . -type f -name libfilcrypto.a -exec cp -- "{}" $__tmp_dir/filcrypto \;
-    find -L . -type f -name filcrypto.pc -exec cp -- "{}" $__tmp_dir/ \;
+    find -L . -type f -name filcrypto.pc -exec cp -- "{}" $__tmp_dir/filcrypto \;

-    tar -czf $__tarball_output_path $__tmp_dir/*
+    tar -czf $__tarball_output_path -C $__tmp_dir filcrypto

Please comment, and I will revert second option, and reduce PR to first option one-line
