app-crypt/hashcat-6.2.1.ebuild: compile with built-in unrar (USE_SYSTEM_UNRAR=0)

Upstream commit https://github.com/hashcat/hashcat/commit/3cc828ce0adba00c3f3d11fb62494c10bea099f9 introduced -m 23700/23800 (RAR3-p cracking) before releasing v6.2.0.

app-crypt/hashcat-6.2.1.ebuild currently pulls app-arch/unrar and compiles with USE_SYSTEM_UNRAR=1, but there's no trace of hc_decompress_rar in app-arch/unrar-6.0.5 nor in unrar-6.0.6.

Just running the following after installing hashcat-6.2.1 or hashcat-9999 gives an error:

$ hashcat --help
hashcat (v6.2.1) starting...

/usr/share/hashcat/modules/module_23800.so: undefined symbol: hc_decompress_rar

Segmentation fault

To solve the problem compile with the built-in unrar (USE_SYSTEM_UNRAR=0).
