Subject: [PATCH] lib/Makefile: set correct soname for libcryptfs-tpm2

The current soname of libcryptfs-tpm2 is libcryptfs-tpm2.so:
$ readelf -d libcryptfs-tpm2.so.0.7.0 | grep SONAME
0x000000000000000e (SONAME)    Library soname: [libcryptfs-tpm2.so]

The libcryptfs-tpm2.so is a symbolic link of libcryptfs-tmp2.so.0.7.0
and it is not installed by default because it is packaged to dev
package. Then we will encounter an error when run command cryptfs-tpm2:
$ cryptfs-tpm2
cryptfs-tpm2: error while loading shared libraries: libcryptfs-tpm2.so: cannot open shared object file: No such file or directory
$ ldd cryptfs-tpm2 | grep libcryptfs-tpm2
    libcryptfs-tpm2.so => not found

Set the soname to libcryptfs-tpm2.so.$(MAJOR_VERSION) to fix the issue.
