Subject: [PATCH v2] fcntl: Use consistent values for F_[GS]ETOWN_EX

These values were only introduced during this release cycle, so it is
still early enough to get them right.

alpha uses the same values that are in asm-generic/fcntl.h, so just
remove them.

parisc uses the values interchanged for no apparent reason, so remove them
to give us consistency across all architectures.

Ulrich pointed out that using F_LINUX_SPECIFIC_BASE for these make code
less efficient when these values are used in switch statements.
