Static linking with bctoolbox fails when using pkg-config as the
generated bctoolbox.pc file only consists of an '-L' string without any
search path or libraries flags:
```
libtool: link: need path for `-L' option
```
That's because of an typo in mbedtls_library_path. However,
mbedtls_library_path contains a string of the mbedtls libraries
concatenated by an ';' which cannot be parsed by pkg-config.
Therefore, use MBEDTLS_LIBRARY instead of MBEDTLS_LIBRARIES to get
the library path.
Furthermore, add the three mbedtls libraries mbedtls, mbedcrypto, and
mbedx509 to LIBS_PRIVATE so these libraries are added to the
Libs.private field of bctoolbox.pc.
